When the original DiST® (Dissolved Solids Tester) was first introduced, conductivity and total dissolved solids measurements became easy and affordable. The DiST’s ease of use, in combination with its affordability, made it the standard in EC and TDS measurement. Hanna continues the standard in EC and TDS testing with the DiST®5.
This tester includes features such as a replaceable graphite electrode, adjustable TDS ratio, °C or °F measurement, Automatic Temperature Compensation (ATC) with adjustable β, battery level indicator, stability indicator, automatic shut-off and automatic calibration.
The graphite conductivity electrode offers greater accuracy by resisting contamination by salt deposits in the sample. All of these features are packed in a floating, waterproof casing. This 3-in-1 tester is unmatched in EC, TDS, and temperature measurements.
- Waterproof and designed to float
- Automatic Temperature Compensation
- HOLD button to freeze readings on the display
- BEPS Alerts the user of low battery power that could adversely affect readings
