Turbidity is a critical parameter in evaluating water quality. Elevated turbidity may indicate microbial contamination or poor filtration. In natural waters, it helps assess ecological balance, while in treated wastewater, it's essential for regulatory compliance.

The HI88713 uses infrared light to eliminate interference caused by colored samples—a significant advantage over white light EPA methods. This ensures accurate readings whether analyzing drinking water, process fluids, or wastewater.

ISO 7027 outlines optical requirements for turbidity meters, depending on the concentration being measured:

Diffuse Radiation (Low Turbidity: 0–40 FNU)

  • Infrared wavelength: 860 nm
  • Bandwidth: ≤ 60 nm
  • Incident beam convergence: ≤ 1.5°
  • Detection angle: 90° ±2.5°
  • Aperture angle: 20°–30°

Radiant Flux Attenuation (High Turbidity: 40–4000 FAU)

  • Infrared wavelength: 860 nm
  • Bandwidth: ≤ 60 nm
  • Incident beam convergence: ≤ 2.5°
  • Detection angle: 0° ±2.5°
  • Aperture angle: 10°–20°

The HI88713 fully conforms to these criteria, making it an ideal choice for labs and water treatment professionals requiring ISO-compliant precision.

Principle of Operation

The HI88713 operates using an advanced optical system designed to minimize stray light and maximize measurement accuracy. It uses a combination of light scattering and transmitted light detection depending on the selected mode:

• Non-ratio mode: Measures turbidity based on the signal from the 90° scattered light detector.
• FAU mode: Calculates turbidity from the transmitted light reaching the 180° detector.
• Ratio mode: Combines signals from both detectors to correct for color interference and other anomalies.

The instrument’s lower detection limit is determined by stray light. Thanks to its precision-engineered optics, the HI88713 provides highly accurate results, even at extremely low turbidity levels. This makes it a reliable tool for regulatory testing, environmental monitoring, and high-purity water systems.
