Grocheck EC/TDS and Temperature Monitor (Low Range) - HI993301

SKU: HI993301-01


The HI993301 has a large, dual-level, backlit LCD and displays instantaneous readings of both EC/TDS and temperature, even from a distance.

  • HOLD button to freeze readings on the display
  • Waterproop
  • Backlit, graphic LCD display                         

The HI993301 is a combined EC/TDS/temperature meter specially designed to meet the needs of growers in greenhouses and hydroponic applications.  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 12V DC power supply
