Gro'Chek® EC and TDS Meters- Continuous monitoring for growing media
- Rugged and water resistant
- Automatic temperature compensation
These state-of-the-art meters have been engineered with a host of features to suit the aggressive environments commonly found in agricultural applications. To make these indicators ideally suited for growers, the housings and cable connections have been sealed against vapor and humidity. Problems due to low batteries and battery changes have been solved with a 12 VDC power supply included with the meter. You can simply hang the meter right above the sample to be monitored or take it with you for spot checking. Select HI 983301N for TDS measurements with the common 0.7 TDS conversion factor (4-4-2) or HI 983301N/5 which uses a 0.5 conversion factor. Both the TDS and EC meters come with a probe specifically made for horticultural & hydroponics applications. The probe compensates for temperature variation automatically, is easy to clean and is very stable, needing little maintenance.
