As light passes through, suspended particles cause it to scatter in multiple directions. The degree and pattern of this light scattering are influenced by factors such as the wavelength of the incident light, the physical characteristics of the particles (size and shape), their refractive index, and the sample's inherent color. The turbidity analyzer's optical system strategically employs an infrared LED as a stable light source and a dedicated scattered light detector positioned at a 90° angle to precisely measure the intensity of the scattered light.\u003c\/p\u003e\n\u003cp style=\"font-family: 'Open Sans', sans-serif; font-weight: 300;\"\u003eA critical factor in achieving accurate low-range turbidity measurements is minimizing stray light – light detected by the sensor that isn't a result of particle scattering.

During fermentation, suspended solids create unrefined wine that often appears turbid or hazy. This \"protein haze\" primarily results from positively charged proteins like Thaumatin-like proteins (TLPs) and chitinases, which can aggregate and form visible flocculent clouds.\u003c\/p\u003e\n            \u003cp style=\"font-size: 1.05rem; font-family: 'Open Sans', sans-serif; font-weight: 300;\"\u003eBefore bottling, protein stabilization is essential for white wines and certain light reds\/rosés. Bentonite, a volcanic clay fining agent, effectively clarifies wine. However, precise application is critical to avoid negative impacts such as excessive lees formation, reduction of tannins, or loss of color. It's vital for winemakers to conduct laboratory trials using the same bentonite batch and preparation method as they intend to use in the cellar, given variations in bentonite types and protein removal capacities.\u003c\/p\u003e\n            \u003cp style=\"font-size: 1.05rem; font-family: 'Open Sans', sans-serif; font-weight: 300;\"\u003eWhile red wines generally face fewer protein stability issues due to higher phenol concentrations that bind and precipitate unstable proteins, bentonite is still often added to reduce colloidal particles and enhance filterability. The Hanna HI83749 empowers winemakers to determine initial wine turbidity. By adding the HI83749-20 Bentocheck Solution and taking a second turbidity measurement, you can quickly assess protein stability. If the second reading is less than the initial plus 2 NTU, your wine is stable. Otherwise, precise fining trials can be performed to determine the exact bentonite dosage needed, leading to cost savings and preventing undesirable stripping of wine flavor, body, and color.\u003c\/p\u003e\n        \u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"border-bottom: 1px solid #e0e0e0; margin-bottom: 40px; padding-bottom: 40px; display: flex; flex-wrap: wrap; align-items: center; gap: 40px;\"\u003e\n        \u003cdiv style=\"flex: 1 1 500px; min-width: 300px;\"\u003e\n            \u003cimg style=\"width: 100%; height: auto; object-fit: contain; border-radius: 8px;\" alt=\"HI83749 Portable Turbidity Meter Optical System Diagram\" src=\"https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/light-diagram-2.png?width=618\u0026amp;name=light-diagram-2.png\" srcset=\"https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/light-diagram-2.png?width=309\u0026amp;name=light-diagram-2.png 309w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/light-diagram-2.png?width=618\u0026amp;name=light-diagram-2.png 618w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/light-diagram-2.png?width=927\u0026amp;name=light-diagram-2.png 927w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/light-diagram-2.png?width=1236\u0026amp;name=light-diagram-2.png 1236w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/light-diagram-2.png?width=1545\u0026amp;name=light-diagram-2.png 1545w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/light-diagram-2.png?width=1854\u0026amp;name=light-diagram-2.png 1854w\" sizes=\"(max-width: 618px) 100vw, 618px\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv style=\"flex: 1 1 500px; min-width: 300px; display: flex; flex-direction: column; gap: 20px;\"\u003e\n            \u003cdiv\u003e\n                \u003ch4 style=\"font-weight: 400; margin-bottom: 8px; font-family: 'Open Sans', sans-serif;\"\u003ePrinciple of Operation for Wine Turbidity\u003c\/h4\u003e\n                \u003cp style=\"font-size: 1rem; font-family: 'Open Sans', sans-serif; font-weight: 300;\"\u003eThe HI83749 turbidity meter precisely measures wine turbidity by passing a light beam through the sample, which then scatters in all directions.

While historically considered an aesthetic concern, substantial evidence now confirms that effective turbidity control acts as a robust safeguard against waterborne pathogens. In natural environments, turbidity measurements are essential for assessing general water quality and its suitability for aquatic life. Furthermore, monitoring turbidity is vital in wastewater treatment processes to ensure compliance with regulatory standards. Turbidity is an optical property that describes how light is scattered and absorbed rather than transmitted through a liquid, primarily due to suspended solids. Higher turbidity indicates greater light dispersion, and even the purest liquids will exhibit some degree of light scattering, meaning achieving absolute zero turbidity is practically impossible.\u003c\/p\u003e\n                \u003cp style=\"font-size: 1.05rem;\"\u003eDrinking water treatment facilities that draw water from surface sources like lakes and rivers are mandated by the EPA to continuously monitor and report turbidity levels. EPA Method 180.1 sets forth specific requirements for nephelometers and outlines reporting protocols, including an applicable range of 0-40 NTU, a tungsten lamp light source operating between 2200-3000°K, a maximum light path of 10 cm, and a 90° detector with a spectral peak response between 400 nm and 600 nm.

As light passes through, it is scattered in various directions. The intensity and pattern of this scattered light are influenced by several factors, including the light's wavelength, as well as the size, shape, refractive index, and color of the particles suspended within the sample. The HI98703's advanced optical system integrates a tungsten filament lamp with both a 90-degree scattered light detector and a 180-degree transmitted light detector to capture these crucial interactions.\u003c\/p\u003e\n            \u003cp style=\"font-size: 1rem;\"\u003e\u003cstrong\u003eRatio Turbidimetry for Enhanced Accuracy:\u003c\/strong\u003e In the ratio turbidimeter mode, the instrument's microprocessor intelligently calculates the Nephelometric Turbidity Unit (NTU) value.

While historically considered an aesthetic characteristic, robust evidence now demonstrates that effective turbidity control acts as a vital safeguard against waterborne pathogens. In natural environments, turbidity measurements are commonly performed to gauge overall water quality and its suitability for supporting aquatic organisms. Historically, wastewater monitoring and treatment were primarily driven by turbidity control, and even today, measuring turbidity at the end of the wastewater treatment process is essential for verifying compliance with stringent regulatory standards.\u003c\/p\u003e\n\u003cp style=\"font-size: 1rem;\"\u003e\u003cstrong\u003eThe Nature of Turbidity:\u003c\/strong\u003e Turbidity in water is fundamentally an optical property that causes light to be scattered and absorbed rather than transmitted directly through the liquid. The scattering of light is predominantly caused by the presence of suspended solids. Consequently, higher turbidity levels correlate directly with a greater amount of scattered light. It is important to note that even highly purified liquids will exhibit some degree of light scattering, as a true \"zero turbidity\" solution is practically unattainable.\u003c\/p\u003e\n\u003cp style=\"font-size: 1rem;\"\u003e\u003cstrong\u003eISO Method for Turbidity Measurement:\u003c\/strong\u003e The ISO standard for turbidity measurement, as employed by the HI98713, utilizes an infrared wavelength of light (860 nm) that falls outside the visible spectrum. The primary advantage of this ISO method over the EPA method (which uses a tungsten lamp producing visible light) is its significant reduction of color interference. Since the ISO method operates outside the visible wavelength range, the color inherent in a sample does not absorb light and thus does not interfere with the turbidity measurement, ensuring more accurate results for colored samples. (Note: The USEPA typically prefers tungsten lamps for drinking water as it is expected to be clear and they offer better accuracy at very low ranges).\u003c\/p\u003e\n\u003cp style=\"font-size: 1rem;\"\u003e\u003cstrong\u003eISO 7027 Requirements:\u003c\/strong\u003e The requirements for an optical turbidity meter measuring diffuse radiation in low-range applications (e.g., drinking water), expressed in Formazin Nephelometric Units (FNU) according to ISO 7027, are highly specific:\u003c\/p\u003e\n\u003cul style=\"font-size: 1rem; line-height: 1.5; list-style-type: disc; margin-left: 20px;\"\u003e\n\u003cli\u003eThe wavelength of the incident radiation must be 860 nm.\u003c\/li\u003e\n\u003cli\u003eThe spectral bandwidth of the incident radiation must be less than or equal to 60 nm.\u003c\/li\u003e\n\u003cli\u003eThere must be no divergence from parallelism of the incident radiation, and any convergence should not exceed 1.5°.\u003c\/li\u003e\n\u003cli\u003eThe measuring angle, theta, between the optical axis of the incident radiation and that of the diffused radiation, must be 90° ±2.5°.\u003c\/li\u003e\n\u003cli\u003eThe aperture angle should be between 20° and 30° within the water sample.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"font-size: 1rem; margin-top: 20px;\"\u003e\u003cstrong\u003eCompliance:\u003c\/strong\u003e The HI98713 is designed to meet and exceed all meter criteria specified by ISO 7027, ensuring reliable and compliant performance for your turbidity analysis needs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; gap: 40px; border-bottom: 1px solid #e0e0e0; padding-bottom: 40px; margin-bottom: 40px;\"\u003e\n\u003cdiv style=\"flex: 1 1 500px; min-width: 300px; order: 0; display: flex; flex-direction: column; gap: 20px;\"\u003e\n\u003ch4 style=\"font-weight: 400; margin-bottom: 8px;\"\u003ePrinciple of Operation\u003c\/h4\u003e\n\u003cp style=\"font-size: 1rem;\"\u003e\u003cstrong\u003eOptical Principles of Turbidity Measurement:\u003c\/strong\u003e The HI98713 operates on the fundamental principle that a light beam passing through a sample is scattered in all directions by suspended particles.
