Hanna HI981204 Pool Line ORP/Temperature Tester

Hanna HI981204 Pool Line ORP/Temperature Tester

The Hanna HI981204 Pool Line ORP/Temperature Tester is a waterproof and reliable instrument designed to measure oxidation-reduction potential (ORP) and temperature in pool water and spa systems. Its compact design, high accuracy, and factory calibration make it a practical tool for both professionals and home pool owners.

Key Features

• Fast and Accurate ORP Monitoring
  This tester measures ORP from ±1000 mV with 1 mV resolution and an accuracy of ±2 mV, making it ideal for monitoring chlorine-based disinfection levels.

• Integrated Temperature Measurement
  In addition to ORP, the device also measures temperature from -5.0 to 60.0°C with 0.1°C resolution. As a result, it provides complete insight into water quality conditions.

• Factory-Calibrated and Ready to Use
  The HI981204 arrives pre-calibrated, so you can begin testing immediately. This feature eliminates setup time and simplifies routine use.

• Waterproof and Durable Design
  Built for harsh environments, the tester is completely waterproof and ideal for field or poolside applications. Its compact body ensures easy handling, even with wet hands.

• Efficient Battery Operation
  Powered by four 1.5V batteries, the tester offers up to 250 hours of continuous use. Additionally, the auto-off function conserves power when the device is not in use.
