Field/Laboratory/Industrial Electrochemical Sensors



Dissolved Oxygen : Dissolved Oxygen Probe Conditioner.

Our Model 650 Dissolved Oxygen Probe Conditioner enables the user of any pH meter, which has a millivolt range, to take direct readings of dissolved oxygen. This can be done in either mg/l (ppm) or % of oxygen.

In addition, the Model 650 can be used with any high impedance input voltmeter, multimeter or datalogger.

Not only is this of considerable benefit to a laboratory, offering a quick and easy way of measuring dissolved oxygen, but it also benefits users of portable meters, enabling them to add the measurement of dissolved oxygen to the parameters they are measuring out in the field.

The Model 650 uses the tried and tested R.M.S Galvanic Dissolved Oxygen Probe, which does not require a polarisation voltage and provides stability, accuracy and repeatable results. The probe is temperature compensated and when it becomes necessary to change the membrane, it is a simple task to unscrew the membrane cap, fill a new one with the filling solution provided and screw on to the probe.
