    HM portable Digital COM-300 waterproof  EC Temperature combo taster Meter with superior accuracy Automatic Calibration 

    Product description:

The COM300 is an advanced waterproof combo meter with superior accuracy. The meter measures four parameters: 

    pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS) and temperature. Features include 2 different conductivityconversion factors to convert EC to TDS using the 0.5 (NaCl) or 0.7 (442TM), as well as selectable modes for measurements in the S, mS and ppm scales. The meter incorporates automatic temperature compensation (ATC) to accommodate for discrepancies in temperature that would naturally occur, and also features digital calibration for easy and precise calibration that will yield better results.

         Specifications:    

         EC Range: 0 - 9990 µS; 0 - 9.99 mS

TDS Range: 0 - 8560 ppm (mg/L)

     PH Range:0.0-14.0 pH

Temperature Range: 0.1-50 °C; 32-122°F

Resolution:PH :0.1 pH

                      EC:0-999: 1 µS;1000-9990: 10 µS;0-9.99mS:0.01mS
