Hanna HI98120 ORP/Temperature Tester

Hanna HI98120 ORP/Temperature Tester

The Hanna HI98120 ORP/Temperature Tester is a rugged and waterproof ORP (Oxidation Reduction Potential) and temperature tester designed for accurate field and laboratory measurements. With a compact body and a replaceable platinum electrode, it provides fast, reliable ORP readings along with automatic temperature compensation, making it ideal for water quality professionals, aquarists, and sanitation monitoring.

Key Features

• Accurate ORP Measurement
  This tester measures ORP from ±1000 mV with 1 mV resolution and ±2 mV accuracy. As a result, it is excellent for redox monitoring in water treatment, pools, and disinfection processes.

• Dual ORP and Temperature Readings
  The large LCD displays both ORP and temperature simultaneously, allowing real-time observation of how temperature impacts oxidation reactions.

• Automatic Temperature Compensation
  Readings are adjusted for temperature changes from -5 to 60°C, ensuring greater accuracy across a variety of conditions.

• Factory Calibrated and Ready to Use
  The HI98120 comes pre-calibrated, eliminating setup time. Therefore, it can be used immediately out of the box for quick field checks or spot testing.

• Replaceable ORP Electrode
  Equipped with a HI73120 platinum ORP electrode, the unit allows easy probe replacement, which extends the device’s working life and reduces downtime.

• Waterproof and Portable
  With a compact, IP-rated waterproof design, this tester is ideal for fieldwork in demanding environments. Its slim profile also makes it comfortable to carry and operate.

• Efficient Power Management
  Powered by four 1.5V batteries, it offers approximately 300 hours of use. The auto-off feature helps conserve battery life by shutting off the device after 8 minutes of inactivity.
