HI-98190 Professional Waterproof pH/ORP Meter

The HI-98190 Professional Waterproof pH/ORP Meter, supplied by GAPS Water Treatment, delivers the accuracy of a benchtop instrument in a rugged, portable body. With its IP67-rated enclosure, this meter is built for universal applications—whether you are testing in the lab, out in the field, or in challenging environments.

Advanced Measurement, Everywhere

Designed for ultimate versatility, the HI-98190 measures pH, ORP (when fitted with an ORP probe), and temperature. Thanks to the quick connect HI-12963 titanium pH/temperature probe, swapping sensors for mV or temperature readings is fast and simple. This meter features a backlit graphic LCD for clear, easy-to-read measurements, even in low-light conditions, and offers intuitive use with dedicated and soft keys in multiple languages.

Key Features

  • IP67 Waterproof, Rugged Enclosure: Withstands tough, wet conditions for reliable use anywhere.
  • Measures pH/ORP & Temperature: Switch from pH to ORP measurement by simply exchanging the probe.
  • Quick Connect Probe: The HI-12963 titanium-bodied pH electrode with built-in temperature sensor attaches securely via a DIN connector.
  • CAL Check™: Alerts you to calibration problems, electrode status, and buffer contamination.
  • Automatic/Manual Temperature Compensation: Ensures precision—sensors include a temperature probe for accurate, compensated readings.
  • Backlit Graphic LCD: High-resolution display remains visible in all conditions.
  • Intuitive Keypad: Dedicated buttons for GLP info, range, calibration, and backlight for smooth operation.
