The Pyxis ST-601 inline probe measures mass/mass concentration of chlorine dioxide (ClO2) in realtime between the range of 0.01% to 0.35%.
PRODUCT
ST-601
(ClO2 sensor)
The Pyxis ST-601 inline probes are uniquely designed to measure mass/mass concentration of chlorine dioxide (ClO2) in realtime between the range 0.01-0.35%. They measure the optical absorbance of the ClO2 solution using a UV light source. The probes have a built-in reference light source and a reference light detector in addition to the main light source and main light detector. They can be connected to any device that accepts an isolated or non-isolated 4-20mA input or RS-485 Modbus. As with all Pyxis inline sensors, the ST-601 probes can be wirelessly accessed via Bluetooth when used in conjunction with the MA-WB Bluetooth Adapter or PowerPACK series auxiliary box and the uPyxis App for mobile phones and PCs.
