Hanna HI981214 Pool Line ORP/pH/Temperature Tester

Hanna HI981214 Pool Line ORP/pH/Temperature Tester

The Hanna HI981214 Pool Line ORP/pH/Temperature Testere is a versatile 3-in-1 tester designed for precise monitoring of pH, ORP (oxidation-reduction potential), and temperature in pool and spa water. With its rugged waterproof design and user-replaceable electrode, it is an ideal tool for professionals and pool owners who need fast and reliable water quality measurements.

Key Features

• All-in-One Water Quality Testing
  This device combines pH, ORP, and temperature measurements in a single, compact unit. As a result, it saves time and simplifies routine pool maintenance.

• Accurate and High-Resolution Readings
  Measure pH from -2.00 to 16.00 with 0.01 resolution and ±0.05 accuracy, and ORP from ±1000 mV with 1 mV resolution. These precise measurements help ensure your pool is safe and properly balanced.

• Automatic Temperature Compensation (ATC)
  Readings are automatically adjusted based on temperature from -5.0 to 60.0°C, improving accuracy even under changing weather conditions.

• User-Friendly Calibration
  The pH sensor supports automatic one- or two-point calibration using two standard buffer sets. Meanwhile, ORP is factory-calibrated, so no additional setup is required.

• Replaceable Electrode Module
  The replaceable combination sensor extends the life of the device and makes maintenance easy. Therefore, it’s a cost-effective solution for long-term use.

• Waterproof and Portable
  Built to withstand outdoor environments, the tester features a waterproof body and compact form. You can confidently use it poolside or in humid conditions.

• Long Battery Life and Auto-Off
  The HI981214 runs on four 1.5V batteries for up to 250 hours, with an auto-off function that helps preserve battery life during periods of inactivity.
