Conductivity (EC) Meter Total Dissolved Solids and Temperature
Ideal for all water quality testing, water treatment, colloidal silver, laboratory and scientific testing, swimming pools and spas, ecology testing, boilers and cooling towers, water treatment and much more. The COM-100 is a professional level EC / TDS Electrical Conductivity meter at an unbeatable price.
It measures electrical conductivity (EC), total dissolved solids (TDS), and temperature.
Scales: Four scales: μS, mS, ppm, ppt (mS and ppt are new).
Three different nonlinear EC-to-TDS conversion factors (KCl, 442TM, NaCl).
Automatic Temperature Compensation (ATC) using three temperature coefficients
Waterproof housing Waterproof (IP-67 rating)
Measuring range: 0-9990 μS; 0 – 8560 ppm; 0-9.99 mS; 0-8.56 ppt
Digital calibration (push-button) to any point within the meter’s range
Auto power off function, data hold function and low battery indicator
Display: large, easy-to-read LCD display including simultaneous temperature readout.
Replaceable sensor (SP-C1 model)
Factory calibration: The COM-100 meter is calibrated with a 1413 μS solution. The meter can be recalibrated with digital calibration using the push buttons instead of a screwdriver.
Includes cover, batteries and cord.
