Hanna HI98318 GroLine waterproof EC/TDS/Temperature test

Hanna HI98318 GroLine EC/TDS/Temperature Tester

The Hanna HI98318 GroLine waterproof EC/TDS/Temperature test is a compact and waterproof tester designed specifically for electrical conductivity (EC), total dissolved solids (TDS), and temperature measurement in hydroponics, greenhouse cultivation, and nutrient solution monitoring. Built with Hanna’s trusted precision and ease-of-use, this tester helps growers achieve optimal results by ensuring accurate control of nutrient levels and water quality.

Features

• 3-in-1 Nutrient Monitoring Solution
  Simultaneously measures EC up to 6.00 mS/cm, TDS up to 3999 ppm, and temperature up to 50.0°C, making it a comprehensive tool for growers. As a result, users can manage water and nutrient conditions with confidence.

• Dual TDS Conversion Factors
  Offers two selectable conversion factors: 0.5 (500 ppm scale) and 0.7 (700 ppm scale). This flexibility ensures compatibility with different hydroponic systems and grower preferences.

• High Accuracy and Resolution
  Provides a ±2% full scale accuracy for EC and TDS and ±0.5°C for temperature, with fine resolution of 0.01 mS/cm (EC) and 10 ppm (TDS). Therefore, even slight changes in nutrient concentration can be detected and corrected.

• Automatic Temperature Compensation (ATC)
  Readings are automatically adjusted to reflect real-time temperature changes from 0 to 50°C. Consequently, measurements remain consistent and reliable regardless of environmental conditions.

• Ergonomic, Waterproof Design
  Designed to perform in wet, humid environments, this tester features a slim, IP67 waterproof housing, weighing only 75 g. Moreover, its compact size makes it ideal for both field and indoor growing spaces.

• Simple and Fast Operation
  The GroLine tester is ready to use with intuitive controls, enabling quick readings and easy calibration. As such, it’s suitable for both professionals and hobbyists.
