FEATURES
*Measures electrical conductivity (EC), total dissolved solids (TDS). Exellent for nutrient testing.
*Four scales: EC: µ S, mS; TDS: Ppm, ppt
*Automatic Temperature Compensation (ATC)
*Water resistant
*Measurement Range: 0-9990 µ S; 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 µ S solution. The meter can be recalibrated with digital calibration using the push buttons.
*Includes a protective cap and batteries.
