REDOX (Reduction-Oxidation) Testing

REDOX Testing allows you to measure the REDOX potential. The REDOX potential is a measure of the availability of free electrons.  More free electrons leads to reduction and a lack of free electrons leads to oxidation

The measurement is a very simple one and is similar to the measurement of pH but instead of using a Glass pH electrode a Platinum sensor is used.

The platinum sensor is non specific and will not identify the source of the electrons. It will however provide an idea of whether the solution is oxidising or reducing and can indicate its REDOX capability.  REDOX is a potential difference measurement in mV and therefore requires a reference electrode used in conjunction with the platinum sensor.

We have both Lab REDOX Electrodes    and Process REDOX Electrodes

The meter used can be a pH meter with a millivolt mode and the range of extremes is within =/- 1000mv. To give you and idea tap water would normally be around 100mv whilst a swimming pool containing approximately 2ppm Chlorine (highly Oxidising) would be around 600mv (approx).

Oxidising or Reducing power increases 10 times for every 59 mV (approx.)  as governed by the Nernst equation.

EDT directION manufacture many REDOX Testing products  which are readily available for rapid delivery.
