Multimeter for Conductivity, TDS, Temperature & Salinity

The waterproof ExStik Conductivity/TDS/Salinity Meter offers one high accuracy multi-range sensor which measures four parameters (Conductivity, TDS, Salinity and Temperature).


  • Auto ranging meter offers 3 ranges to measure from pure water to salinity solution to waste, boiler and cooling water using the same conductivity cell.
  • 6 units of measure: µS/cm, mS/cm, ppm, ppt, mg/L, and g/L. Internal memory stores up to 15 labelled readings for easy recall.
  • Self-calibration on power up.
  • Waterproof design to withstand wet environment – meets IP57 Standard.
  • Easy to replace Conductivity cell module.
  • Auto ranging meter offers 3 ranges of measurements from tap water to wastewater and any aqueous solution requiring conductivity, TDS or Salinity measurements.
  • High accuracy multi-range conductivity cell measures
  • Conductivity, TDS, Salinity and Temperature.
  • Adjustable Conductivity to TDS ratio factor from 0.4 to 10– conveniently calculates the TDS value.
  • Large 3-1/2 digit (2000 count) Digital display with analog bar graph to indicate sample trends.
  • Data Hold, Auto Power Off and low battery indication.
  • Automatic Temperature Compensation of 2% per ºC.
  • Simultaneous display of Conductivity, TDS, or Salinity plus Temperature.
  • Self-calibration of electronics on power up.
  • EC400 includes meter and Conductivity cell*, protective sensor cap, sample cup with cap, four CR2032 button batteries and 48” (1.2m) neck strap.
