Dissolved Oxygen Sensor
Description
Options
- ST-772T: Standard DO Sensor with built in temperature and pressure sensor
- ST-773: Inexpensive DO Sensor without pressure sensor
- ST-774: Ultra low DO Sensor, popular in boiler application
The Pyxis Lab® ST-772, ST-773 and ST-774 optical luminescent dissolved oxygen (DO) sensor is based on the principle of ‘Fluorescence Quenching’ to determine dissolved oxygen content in water. This sensor incorporates Pyxis’ advanced technology in the field of fluorescence detection, using Blue/Red Light Detection technology with excitation and reference light sources to offer a wide detection range and extremely low detection limit. The sensor also integrates temperature and pressure sensors to perform compensation for the measurement of dissolved oxygen based on ambient environmental conditions.
The ST-772/3/4 offers an easily replaceable, front loading DO membrane cap that has been independently developed by Pyxis Lab® with a typical service life of up to 2 years. This unique DO membrane cap design incorporates a black microporous PTFE membrane material designed to provide extreme scratch resistance, extended life span and simple replacement. The flat front-end design makes this platform less prone to contamination or fouling and is very easy to clean.
The sensor body is composed of 304 stainless steel or PVC and is well suited for aggressive industrial application use.
