Professional Multi-meter for Conductivity, TDS & Temperature

The Jenway 470 Conductivity/TDS Meter is a general purpose hand held meter offering a wide measuring range, which is further complimented by the auto-ranging function that ensures results are displayed with the highest resolution that can be achieved.


  • Automatic range selection for optimum resolution.
  • Automatic or Manual calibration.
  • 32 reading data storage.
  • Conductivity and TDS modes.
  • Power on self-test routine.

Calibration can be carried out automatically against standard solutions at 10µS, 84µS, 1413µS and 12.88mS or a manual calibration can be made against any other standard value.

Standard conductivity measurements can be made quickly and easily using the default settings, but for more complex applications a full range of adjustments can be made. The reference temperature can be set to 18, 20 or 25°C and the temperature coefficient set from 0 to 4%/°C. When using the alternative TDS range the E/C ratio can be set from 0.5 to 0.8 to ensure conformance with all operating procedures.

A simple, dual function memory bar enables up to 32 readings to be stored and recalled from the non-volatile internal memory.

An indication of battery life is also permanently shown on the display. An automatic switch off facility helps to conserve battery life. This product is ideal for field or any portable situation.
