DO SENSOR
Low ppb Measurement

Hydro-Air DO sensor is membrane based and uses polarographic technology to determine dissolved oxygen levels. The sensor generates a potential, mV, related to the dissolved oxygen in contact with membrane. It also has a built-in thermistor for automatic temperature compensation.
The sensor is made up of stainless steel 316L body with high quality membrane. The dual-layer membrane is reinforced with stainless steel mesh to resist damage and extend the longevity of the sensor. The modular design of the membrane assembly makes regular maintenance.
