Hanna Instruments – HI98312 DiST® 6 EC/TDS/Temperature Tester (0.00 to 20.00 mS/cm)

The HI98312 DiST® 6 is a high-range EC/TDS/temperature tester designed for professional water quality monitoring. It measures electrical conductivity (0–20.00 mS/cm), TDS (0–10.00 ppt), and temperature (0–50°C / 32–122°F) with high precision. The tester includes a replaceable HI73311 graphite EC/TDS electrode, automatic one-point calibration for EC and TDS, user-selectable conversion factor, and adjustable temperature compensation coefficient ß, making it suitable for laboratories, aquaculture, hydroponics, and industrial water applications. Its slim, ergonomic design, HOLD button, and waterproof casing ensure reliable and convenient measurements in both field and lab conditions.

  • Measures high-range EC, TDS, and temperature in one compact instrument
  • High accuracy: ±2% F.S. for EC/TDS, automatic temperature compensation
  • Replaceable HI73311 graphite EC/TDS electrode
  • Waterproof IP67 casing, ergonomic design, HOLD button for readings

Description

The HI98312 DiST® 6 EC/TDS/Temperature Tester is built for accurate monitoring of high-range water conductivity, dissolved solids, and temperature. It measures EC up to 20.00 mS/cm and TDS up to 10.00 ppt, making it ideal for applications such as industrial water treatment, aquaculture, and hydroponics. Automatic one-point calibration and user-selectable EC-to-TDS conversion factor ensure precise measurements. The adjustable temperature compensation coefficient ß provides flexibility in various testing conditions, while °C or °F readings make interpretation simple.

Engineered for durability and ease of use, the tester features a waterproof casing that floats, a large LCD displaying stability indicator, calibration tags, and low-battery alert, and a HOLD button to freeze readings. Its two-button operation and Battery Error Prevention System (BEPS) ensure smooth, reliable performance in the field or lab, while the replaceable graphite EC/TDS electrode extends the lifespan of the instrument.
