Sensor for the measurement of peracetic acid C₂H₄O₃, surfactants and conductive acids are tolerated.

• Measured variable(s): Peracetic acid
• Calibration:
  • DIN 38409-15 “Determination of hydrogen peroxide”
  • ISO/DIS 7157 “Determination of hydrogen peroxide content – Titrimetric method”
• Interferences:
  • ClO₂ increases the reading
  • H₂O₂ has a very minor influence on the reading, lowers the PES signal
  • O₃ increases the reading significantly
• pH range: 1-6
• Pressure range: 0‒1 bar, no pressure surges and/or fluctuations
• Temperature range: 0‒60 °C
• Integrated automatic temperature compensation
• Run-in period during first start-up: 30‒180 min
• Response time: T90 approx. 3.5 min at 10 °C, approx. 45 s at 50 °C
• Flow rate: approx. 30 l/h, low flow dependence
• Shaft length: standard 175 mm (mA version up to 220 mm)
• Connection: standard 4-pin plug; mA version 2-pole terminal, M12 socket or modbus RTU with M12 socket
• Material: PEEK, stainless steel 1.4571
