With 12 advanced methods to measure 11 essential water quality parameters, this meter uses a cutting-edge optical system with LEDs, interference filters, and dual detectors to ensure unmatched accuracy and repeatability.\u003c\/p\u003e\n\u003cp\u003eReliable disinfection is critical for healthy recreational water systems. This instrument helps maintain ideal chlorine, bromine, pH, alkalinity, and calcium hardness levels—key to avoiding harmful bacteria, algae, corrosion, or scale. For added efficiency, the built-in digital pH input allows rapid pH analysis with intelligent electrode recognition and hot-swapping.\u003c\/p\u003e\n\u003cp\u003eEducators and advanced users benefit from the absorbance mode, which supports custom concentration plots and Beer-Lambert Law demonstrations at three selectable wavelengths. Dual USB ports streamline data transfer or power supply, while the integrated rechargeable battery ensures operation even on the move.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: Reagents are not

quality analysis, engineered to deliver precise pH, ORP (Oxidation-Reduction Potential), and Ion-Selective Electrode (ISE) measurements with unmatched reliability in demanding aquatic environments. This robust and waterproof meter comes equipped with a durable titanium body pH electrode, featuring an integrated temperature sensor for highly accurate readings with automatic temperature compensation, ensuring consistent performance for pool and spa management.\u003c\/p\u003e\n\u003cp style=\"font-size: 0.95rem;\"\u003eEnsure crystal-clear pool water with confidence thanks to the innovative CAL Check™ feature. This intelligent system proactively monitors your pH calibration process, providing real-time alerts for potential issues such as electrode cleaning needs, breakage, or buffer contamination. After calibration, the meter displays an intuitive probe condition percentage (0-100%), offering immediate insight into your electrode's health. You can perform precise five-point pH calibrations using seven preprogrammed standard buffers, including those ideal for pool applications, or utilize five custom buffer options for specialized requirements, guaranteeing measurement accuracy in diverse pool and spa chemistries.\u003c\/p\u003e\n\u003cp style=\"font-size: 0.95rem;\"\u003eBeyond standard pH, the HI981914 excels in advanced water chemistry, simplifying ISE measurements with preprogrammed settings for various common ions found in pool and spa systems. Easily select your target ion, and the meter automatically applies the correct ion charge and molar weight, while also displaying the ISE slope percentage for detailed analysis. The meter supports multi-point ISE calibrations and offers a wide array of measurement units like ppm, ppb, and mg\/L, essential for managing precise chemical dosages and maintaining optimal water balance in aquatic environments.\u003c\/p\u003e\n\u003cp style=\"font-size: 0.95rem;\"\u003eStreamline your daily operations with the convenient AutoHold function, which automatically freezes stable readings on the display, making data recording effortless for busy pool and spa professionals. An \"out of calibration range\" warning can be activated to alert you if measurements fall outside the calibrated pH values, ensuring data integrity. The meter's log-on-demand mode allows you to record and save up to 300 samples (100 each for pH, mV, and ISE), with all measurement data and associated GLP (Good Laboratory Practice) information easily transferred to a PC for comprehensive record-keeping and analysis of water quality trends.\u003c\/p\u003e\n\u003cp style=\"font-size: 0.95rem;\"\u003eAccess immediate support directly on your device with the dedicated help button, providing context-specific information for any screen. The high-contrast graphic LCD offers exceptional readability in diverse lighting conditions, from bright outdoor sunlight by the poolside to dimly lit mechanical rooms, enhanced by its crisp backlight. Navigate the meter intuitively using a combination of dedicated and virtual keys, with multiple language options for enhanced user convenience. The HI981914 is supplied in a compact, durable thermoformed carrying case, expertly designed to securely hold all essential components for seamless field measurements at any pool or spa facility, ensuring portability and instrument protection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003chr style=\"border-top: 1px solid #e0e0e0; margin: 20px 0; border-width: 0.5px;\"\u003e\n\u003c\/div\u003e\n\u003csection style=\"font-family: 'Open Sans', sans-serif; font-weight: 300; padding: 20px; text-align: center;\"\u003e\n\u003ch3 style=\"font-size: 2rem; font-weight: 400; margin-bottom: 30px;\"\u003eIntuitive On-Screen Features for Pool \u0026amp; Spa Management\u003c\/h3\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; justify-content: center; gap: 30px;\"\u003e\n\u003cdiv style=\"flex: 1 1 250px; max-width: 300px; display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg style=\"width: 100%; height: auto; max-width: 200px; object-fit: contain; margin-bottom: 20px; border-radius: 8px;\" alt=\"Setup Screen for Pool \u0026amp; Spa Meter\" src=\"https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/set-up-screen-hi98191-hi98190.jpg\"\u003e\n\u003ch4 style=\"font-size: 1.3rem; font-weight: 400; margin-bottom: 10px;\"\u003e\u003cstrong\u003eCustomizable Setup for Aquatic Environments\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp style=\"font-size: 0.95rem;\"\u003eOur extensive setup screen offers a wide range of configurable options crucial for pool and spa environments, including time, date, temperature units (°C or °F), and language selection for easy navigation and help guides.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 250px; max-width: 300px; display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg style=\"width: 100%; height: auto; max-width: 200px; object-fit: contain; margin-bottom: 20px; border-radius: 8px;\" alt=\"CAL Check™ for Pool \u0026amp; Spa pH Calibration\" src=\"https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/calibration-screen-hi98191-hi98190.jpg\"\u003e\n\u003ch4 style=\"font-size: 1.3rem; font-weight: 400; margin-bottom: 10px;\"\u003e\u003cstrong\u003eCAL Check™ for Reliable Pool pH\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp style=\"font-size: 0.95rem;\"\u003eDetailed CAL Check™ messages provide real-time guidance during pH calibration, alerting pool and spa technicians to potential problems such as a dirty electrode, a broken probe, or even contaminated buffer solutions, ensuring accurate pH readings essential for chlorine effectiveness and swimmer comfort.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 250px; max-width: 300px; display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg style=\"width: 100%; height: auto; max-width: 200px; object-fit: contain; margin-bottom: 20px; border-radius: 8px;\" alt=\"GLP Data for Pool Water Quality Records\" src=\"https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/glp-screen-hi98191-hi98190.jpg\"\u003e\n\u003ch4 style=\"font-size: 1.3rem; font-weight: 400; margin-bottom: 10px;\"\u003e\u003cstrong\u003eComprehensive GLP Data for Compliance\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp style=\"font-size: 0.95rem;\"\u003eAccess full GLP (Good Laboratory Practice) functions instantly to review critical calibration data, including date, time, offset, slope, and the specific buffers used.
