Hanna HI98118 GroLine Waterproof pH Tester

The Hanna HI98118 GroLine Waterproof pH Tester is a robust, high-precision instrument made for growers and horticulturists. Designed for daily pH monitoring in hydroponic nutrient solutions and soil slurries, this compact tester delivers fast and reliable measurements in any growing environment.

Key Features

• Specialized for Agriculture
  Built for growers, this tester helps monitor root-zone pH—essential for nutrient absorption. As a result, it ensures healthier plants and better yields.

• Waterproof and Field-Ready
  With an IP67 waterproof rating, the HI98118 is ideal for fieldwork, greenhouse use, and any wet environment. Therefore, it’s perfect for hands-on growers.

• High Accuracy and Resolution
  It measures pH from 0.00 to 14.00 with a resolution of 0.01 pH and an accuracy of ±0.2 pH. This ensures that even small pH changes can be detected and corrected promptly.

• Large LCD with Dual Display
  The display shows both pH and temperature readings simultaneously. Additionally, icons guide users during calibration and measurement.

• Replaceable Electrode
  Equipped with the HI1271 slim, screw-type pH electrode, this model allows easy replacement—saving time and reducing long-term cost.

• Automatic Temperature Compensation (ATC)
  Readings are automatically adjusted for temperature variations. This feature improves measurement reliability across fluctuating environments.

• One-Hand Operation and Slim Design
  Lightweight and only 17 mm thick, this tester is easy to use with one hand—even while working around plants or in tight spaces.
