The Hanna HI98191 redefines portable pH, ORP, and ISE measurement with its advanced capabilities and robust design. Engineered for professionals, this waterproof meter comes equipped with the durable HI72911B titanium body pH electrode, featuring an integrated temperature sensor for highly accurate, automatically compensated readings. Its resilient titanium construction offers superior chemical resistance and prevents breakage, ensuring reliability in demanding field conditions.
Achieve unparalleled pH accuracy with the innovative CAL Check™ feature. This intelligent system actively monitors your calibration process, providing real-time alerts for potential issues like probe cleaning needs, breakage, or buffer contamination. After calibration, the meter conveniently displays an overall probe condition percentage (0-100%), offering immediate insight into electrode health. You can perform precise five-point pH calibrations using seven preprogrammed standard buffers or five custom options, ensuring a remarkable pH accuracy of ±0.002 with 0.001 pH resolution.
The HI98191 has 15 different ISE sensors preprogrammed, simplifying ion-selective electrode measurements. Easily select your desired ISE from the menu, and the meter automatically applies the correct ion charge and molar weight, displaying the ISE slope percentage for comprehensive analysis. Users can calibrate ISE measurements up to five points with six standard values, and choose from an extensive array of measurement units including ppm, ppt, g/L, ppb, µg/L, mg/mL, M, mol/L, mmol/L, % w/v, and user-defined options, across an expansive range of 1.00 x 10⁻⁷ to 9.99 x 10¹⁰.
Streamline your data collection with the convenient AutoHold function, which freezes stable readings on the display for effortless documentation or logging. An "out of calibration range" warning can be activated, alerting you if readings fall outside the calibrated pH values. 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 data and associated GLP (Good Laboratory Practice) information easily transferable to a PC using Hanna's HI920015 micro USB cable and HI92000 software.
Access instant assistance with the dedicated help button, providing context-specific information based on your current screen. The high-contrast graphic LCD offers exceptional readability in diverse lighting conditions, from bright sunlight to dimly lit environments, 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 HI98191 is supplied in a compact, durable thermoformed carrying case, thoughtfully designed to securely hold all essential components for seamless field measurements, including the meter, electrode, and beakers.
