Obsolete Dissolved Oxygen Meters

This section covers our historical range of Dissolved Oxygen Instruments - please see the Dissolved Oxygen section from the products menu to see our current range of dissolved oxygen meters

Since 1982 we have supplied different types of dissolved oxygen meters to suit our customers' needs. The common ones are displayed below, note the Dissolved Oxygen controllers are usually part of a family of controllers which usually include pH, Redox Conductivity and Dissolved Oxygen.

We currently offer one of the widest range of controllers to the market. Our controllers all match each other for panel mounting and they include pH, Redox, Conductivity, Resistivity ( for ultra pure water up to 18mΩ ) Solution strength using Electrodeless Conductivity, Dissolved Oxygen, Residual Chlorine, Turbidity, and Specific Ion measurement.

Dissolved Oxygen Meters - Model Aquatronic APWL2, APWCF2, APWCI2

Model Aquatronic APWL2, APWCF2, APWCI2 Surface mounting version of the APP range which were the same instruments in weatherproof enclosures.

Replacement Dissolved Oxygen Meter

Replacement instrument Model OD7685-W DO2 controller which has two on/off control relays and an isolated 0 -20 / 4-20 mA out performs the original.

Dissolved Oxygen Sensor - PVC galvanic sensor

Dissolved Oxygen Sensor - PVC galvanic sensor

PVC galvanic sensor with buffered carbonate filling solution no longer available. Manufacture ceased in the early 1990s, so most sensors are around 15 years old.

Replacement Dissolved Oxygen Sensor

Replace the instrument with the OD7685 and the dissolved oxygen sensor with DES1 DO2 sensor. The original systems have given good service with a low cost of ownership so a similar system should offer the same service.
