Icons provide quick updates on battery life and completed calibration status. Simple button layout and onscreen messages help with calibration and setup menu choices.

Features and Benefits

  • Large, informative screen clearly shows the main information, including conductivity or TDS reading, temperature, meter mode and power source
  • Don't miss a reading—AUTOREAD™ locks in the stable reading on your screen and ready indicator alerts when readings are stable Selectable cell constant
  • Â Selectable reading reference temperatures of 20°C or 25°C for an accurate result
  • Included electrode arm and newly-designed holder make it easier to maintain and place probes into samples
  • Plug the meter into almost any power outlet with the included universal power adapter, or use four AA batteries (sold separately) to run the meter on DC power
  • Non-volatile memory holds up to 50 data points
  • The IP54-rated housing can handle splashes and can be wall-mounted if table space is a problem
  • 3 year meter replacement warranty
