• ㆍProduct Highlights
  
  - UPGRADED! (See below) Ideal for all water quality testing, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more. The COM-100 is a professional level EC/TDS meter at an unbeatable price. Instruction Manual FEATURES
  
  - Measures electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature.
  
  - UPGRADED: Four scales: µS, mS, ppm, ppt (mS and ppt are new)
  
  - Three different non-linear EC-to-TDS conversion factors (KCl, 442TM, NaCl).
  
  - Automatic Temperature Compensation (ATC) using three temperature coefficients
  
  - Waterproof housing (IP-67 rating)
  
  - Measurement 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-off function, data-hold function and low-battery indicator
  
  - Display: large and easy-to-read LCD screen includes simultaneous temperature reading.
  
  - Replaceable Sensor (model SP-C1)
  
  - Factory Calibrated: The COM-100 meter is calibrated with a 1413 µS solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver. Includes a cap, batteries and lanyard.
