The Hanna Hanna HI98127 pHep 4 pH/Temperature Tester is a highly reliable, waterproof pH and temperature tester engineered for field and lab professionals who demand precise, easy-to-use, and portable instruments. Designed for accuracy and convenience, this meter is ideal for applications in agriculture, environmental testing, water treatment, food production, and more.

Key Features

• Dual pH and Temperature Measurement
  The HI98127 offers simultaneous readings of pH and temperature, allowing for efficient, real-time monitoring. As a result, users can make quicker, more informed decisions in the field or lab.

• Waterproof and Floating Design
  Built with an IP67-rated housing, this tester is fully waterproof and floats, ensuring reliability even in harsh or wet environments.

• High Accuracy and Resolution
  The device features 0.1 pH resolution with an accuracy of ±0.1 pH, and temperature resolution of 0.1°C for dependable data collection.

• Automatic Temperature Compensation (ATC)
  Readings are automatically adjusted for temperature variations, improving measurement reliability across different environmental conditions.

• Simple Automatic Calibration
  The tester allows automatic 1 or 2-point calibration using two sets of buffer options:

  • pH 4.01 / 7.01 / 10.01

  • pH 4.01 / 6.86 / 9.18
    This flexibility supports broader application needs.

• Efficient Power Use
  Powered by four 1.5V batteries, the meter provides approximately 300 hours of continuous operation. Furthermore, an auto-off feature preserves battery life by shutting down the unit after 8 minutes of inactivity.

• Compact and Lightweight
  With a slim, ergonomic design, it is easy to hold and operate with one hand. The large LCD screen ensures clear viewing of both pH and temperature readings.
