- Sensors for Peracetic Acid


Graduated measuring ranges 1 – 2,000 mg/l. Measurement of peracetic acid concentration with DULCOTEST sensors: Precise and reliable for disinfection in safety-sensitive applications in the food, pharmaceutical and medical industries. Can also be used in waste water treatment.

Reliable online measurement of peracetic acid – with DULCOTEST sensors.

Our product line of DULCOTEST peracetic acid sensors provides two types of sensor for different measuring ranges.

Your benefits

  • Precise, real-time amperometric measurement for efficient process control
  • Amperometric measuring means no clouding or discolouration
  • Use of sensors if hydrogen peroxide is present without cross sensitivity
  • Use of sensors if dissolved matter, surfactants and film-forming media are present without damage to diaphragm
  • Use of sensors under process conditions with CIP (cleaning in place) and rinsers (bottling)
  • Stable zero point means no drift

  • CIP (cleaning in place)
  • Bottling
  • Disinfection in pharmaceutical and medical technology
  • Waste water treatment

  • Measuring range Type PAA 1-mA-200ppm: 0-200 ppm
  • Measuring range Type PAA 1-mA-2000ppm: 0-2000 ppm
  • Conditions of use: Temperature up to 45 °C, pressure up to 3 bar (30 °C)

Peracetic Acid Sensor PAA 1-mA

Sensor for the measurement of peracetic acid without cross-sensitivity towards hydrogen peroxide. For use in contaminated washing and waste water
