Description

The HI98120 ORP/Temperature Tester is ideal for water quality monitoring, providing accurate ORP measurements and temperature readings from -5.0 to 60.0 °C (23.0 to 140.0 °F). Its replaceable ORP electrode (HI73120) with extractable junction ensures consistent performance and long life. Users can monitor disinfectant effectiveness and water quality in the field with confidence thanks to the large LCD that clearly displays measurement stability, calibration tags, and low battery alerts.

Designed for portability and convenience, the tester features a slim ergonomic design that fits easily in hand or pocket, a HOLD button for easier measurement recording, and a waterproof IP67 casing that floats if dropped in water. The automatic shut-off function and visible battery percentage level make it a practical, reliable tool for field or laboratory applications.
