Description
The HI98318 GroLine EC/TDS meter measures conductivity (0.00–6.00 mS/cm) and TDS (up to 3999 ppm depending on conversion factor) with ± 2% F.S. accuracy. Users can select between 0.5 (500 ppm) and 0.7 (700 ppm)EC to TDS conversion factors, making the tester adaptable to different nutrient standards. The graphite conductivity sensors minimize polarization effects, resulting in improved accuracy and reduced maintenance compared to traditional metal-pin sensors. Single-point automatic calibration can be performed using Quick Cal standard or 1.41 mS/cm solution in standard calibration mode.
Designed for convenience, the meter features fast automatic temperature compensation (0–50°C) with an exposed temperature probe for rapid response. Its slim, lightweight design (75 g) and waterproof housing make it ideal for greenhouse and hydroponic environments. With up to 250 hours of operation from a CR2032 battery and supplied with calibration sachets and protective cap, the HI98318 is ready for immediate field use.
