HI993301 Grocheck EC/TDS and Temperature Monitor (Low Range)
Details
EC/TDS is a combined EC/TDS/temperature meter specially designed to meet the needs of growers in greenhouses and hydroponic applications. You can simply install the meter above the sample to be tested for continuous measurement.
The EC/TDS/Temperature probe has been molded with pipe thread (1/2’’ NPT), which allows the user to attach it to an in-line system. Measurements are accurate and the meter can be calibrated at one point. You no longer need to worry about battery changes either: the unit runs without interruption on 12 VDC power supply
