The ST-600 inline sensor is uniquely designed to measure the real-time mass-over-masss concentration of bleach (Sodium Hypochlorite) by percentage as Chlorine (Cl2). This sensor measures the optical density of the beach solution using a UV light source. In addition to the main light source and detector, the ST-600 has a built-in reference light source and detector. Connect it 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-600 sensor can be wirelessly accessed via Bluetooth® when used with the MA-WB Bluetooth Adapter or PowerPACK Series Auxiliary Box and the uPyxis® Mobile or Desktop App.
