EC laboratory meters

Lab Salinity Sensor

The EC-BT is a research grade, lab meter to measure EC, TDS, salinity and resistivity.

Edaphic Scientific supplies electrical conductivity (EC) and total dissolved salts (TDS) meters for laboratory benchtops across a range of applications including scientific research, aquaculture, soils, water quality, wastewater, laboratories and more. Our EC meters are supplied from the world leading manufacturer, Hanna Instruments. Benefits of our EC meters include:

  • Low cost models for researchers, industry and students
  • Extremely high accuracy up to ±0.01 µS/cm
  • Easy to calibrate and maintain
  • Interchangeable or Multi-parameter to models to measure pH, EC, DO, Redox, ISE, temperature, barometric pressure and more…

Contact us now for a quote and we can usually deliver a pH meter to you within 3 days!

The most popular model is the pH-BT pH Meter. The pH-BT model is a benchtop pH and °C meter. This meter also features a reading stability indicator used during calibration and a measurement memory/memory recall function .

pH measurements are compensated for the temperature effect manually or automatically with the temperature probe. These instruments are equipped with an easy-to-read LCD which shows both the primary reading and ºC.
