EC / TDS Water Conductivity Meter + Temp. Tester HM Digital (HydroTester COM-80)

Ideal for all water purification applications, wastewater regulation, aquaculture, hydroponics, and colloidal silver. Perfect for both consumer or commercial use. Carry one in your pocket or toolbox at all times!

The COM-80 is an economically priced, reliable EC/TDS meter that is ideal for testing applications such as hydroponics & gardening, pools & spas, aquariums & reef tanks, water ionizers, drinking water and more.

• 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.
