Description

The ST-601 inline sensor is uniquely designed to measure the real-time (mass/mass) concentration of Chlorine Dioxide (ClO2). This smart sensor measures the optical absorbance of the ClO2 solution using a UV light source. The sensor has a built-in reference light source and a reference light detector in addition to the main light source and main light detector.

Furthermore, the ST-601 offers an expanded range and a RTD temperature output signal. This feature allows users to measure Chlorine Dioxide as high as 0.35% (mass/mass) and obtain a temperature measurement, useful when required to consider the impact of atmospheric temperature conditions on variable ClO2 concentration readings.

Our ST-601 can be connected to any device that accepts an isolated or non-isolated 4–20mA input or RS-485 Modbus. It also can be monitored, configured and calibrated via uPyxis (if connected to the MA-WB Bluetooth® Adapter).

 Features

  • Can Connect to the Suction or Discharge Side of the Bleach Pump using an Inline Tee or 1/4inch Teflon Tube
  • Calibrate & Configure the Sensor Wirelessly via the uPyxis® App (Only when Connected to the MA-WB Adapter)
  • Diagnostic Information can be Displayed Digitally via Modbus RTU
  • Offers Expanded Range & a Temperature Signal Communicated via 2-Channel 4–20mA and RS-485 Output, Modbus RTU
  • Easy to Remove from your System
