ST-773

Luminescent Dissolved Oxygen Sensor

Description

The Pyxis ST-773 optical luminescent dissolved oxygen (DO) sensor is based on the principle of ‘fluorescence quenching’ to determine the dissolved oxygen content in water. It incorporates Pyxis' advanced technology in the field of fluorescence detection and uses dual Blue/Red light detection technology with excitation and reference light sources, offering a wide detection range and very low detection limit. The sensor also integrates a temperature sensor for compensation of the measurement of dissolved oxygen based on environmental conditions. The ST-773 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 two 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 of the ST-773 makes this platform less prone to contamination or fouling and is very easy to clean and brushable. The sensor body is composed of CPVC and is well suited for aggressive industrial application use. The ST-773 may be utilized in a submersed fixed/floating application or inline with the Pyxis submersion assembly and inline thread/tee accessory options. The ST-773 comes with a 10-meter bulkhead cable as well as 1.5-meter flying lead cable each with 7Pin quick adapters. The sensor output offers both 4-20mA and RS-485 Modbus communication which is Bluetooth enabled when used in conjunction with the MA-WB (7-Pin Bluetooth Adapter).
