The Hanna Instruments HI981914 is the ultimate professional solution for comprehensive pool and spa water 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.
Ensure 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.
Beyond 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.
Streamline 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.
Access 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.
