  • General purpose conductivity monitor
  • Measures a wide range of conductivities
 
Unit Price: $ (USD) 595.00

 

The ET125 can be used to record the conductivity of a solution flowing through tubing with an outer diameter of 1/16 inch (1.6mm). Installation is easy as the customer’s tubing is simply slid into the headstage. It must be connected to either the ER225, ER815 or ER825 hardware units.

The sample doesn't come into contact with the detector electrodes so it is easy to analyse hazardous, corrosive or radioactive liquids. There is no carryover or memory effect from the previous sample. There is no electrode deterioration or polarization.

The ET125 can record conductivities between 20 µS/cm and 200 mS/cm, depending on the inner diameter of the tubing being used. It can be used with many tubing materials, including PEEK and PTFE (Teflon) etc.

The ET125 is in the same family as the:

  • ET130 IC/HPLC C4D Detector Headstage.
  • ET131 Configurable C4D Detector/Monitor Headstage.


The gap between the C4D electrodes is relatively large in the ET125 when compared to the ET130. This enables the ET125 to measure higher conductivities, especially when it is used with tubing with a small internal diameter.
