Grocheck EC/TDS and Temperature Monitor (Low Range) – HI993301
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
TheĀ HI993301Ā is a combined EC/TDS/temperature meter specially designed to meet the needs of growers in greenhouses and hydroponic applications. Ā Install the meter above the sample to be tested for continuous measurement.
The EC/TDS/Temperature probe has been molded with pipe thread (½” 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.
