HM Digital Waterproof COM-80 EC/TDS HydroTester
- Waterproof Rating: IP-65. Do not drop the meter into water since it is not rated to the IP-67 rating.
FEATURES:
Measures electrical conductivity (EC), total dissolved solids (TDS). Exellent for nutrient testing. Four scales: EC: µS, mS; TDS: ppm, ppt Automatic Temperature Compensation (ATC) Water resistant Measurement Range: 0-9990 µS; 0-5000 ppm; 0-9.9 mS; 0-5.0 ppt Digital Calibration (push button) to any point within the meter's range Auto-off function, data-hold function and low-battery indicator Display: large and easy-to-read LCD screen includes simultaneous temperature reading. Factory Calibrated: The COM-80 meter is calibrated with a 1413 µS solution. The meter can be recalibrated with digital calibration using the push buttons. Includes a protective cap and batteries.
