Dissolved Oxygen Monitors

Dissolved Oxygen monitors

Envitech offers a range of optical Dissolved Oxygen monitors for process, wastewaters and natural watercourses.

These Optical DO sensors are of an innovative design with No membranes or caps. This means No consumables costs, resulting in a lower cost of ownership.

This type of sensor is simpler to maintain and is more robust because of the solid state technology. The range of instrumentation using this method includes fixed site and hand-held devices for use in many different applications.

dissolved oxygen monitors


MJK have added an optical dissolved oxygen measurement sensor to their range of analysers. This analyzer is a DO system which combines the benefits of the optical sensor with the flexibility and connectivity of the MJK converter. The specs for this system include accuracy of 1% or 0.02ppm, resolution of 0.02ppm and a range of 0-25ppm (temperature range 0-50degC). Co-operation between the sensor manufacturer and transmitter manufacturer has resulted in a powerful and cost-effective solution.
