DULCOTEST® Sensors for Peracetic Acid

Graduated measuring ranges 0.2 – 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.

Product description

Reliable online measurement of peracetic acid with DULCOTEST® sensors.

Our product line of DULCOTEST® peracetic acid Peracetic acid is particularly used in the food and beverage industry, but also for disinfection in ... more in the glossary 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

Field of application

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

    Peracetic Acid Sensor PAA 1-mA

    Sensor for measuring peracetic acid without cross-sensitivity to hydrogen peroxide. For disinfection in contaminated water from the washing of food and from cleaning processes (e.g. CIP).

    Your benefits

    • Measured variable: Peracetic acid, without cross-sensitivity towards the accompanying chemical, hydrogen peroxide
    • Diaphragm-covered sensor minimises faults caused by changing flow or ingredients in the water
    • Resistance to films of dirt by pore-free diaphragm

    PAA 1-mA-2000 ppm10…2,000 mg/l1022507

    Note: a mounting kit (order no. 815079) is required for initial fitting of the sensors in the in-line probe housing DLG III.

    Peracetic acid sensor PAA 2-3E

    Sensor for measuring even low peracetic acid concentrations without cross-sensitivity to hydrogen peroxide, even in waste water (pre-cleaned).

    Your benefits

    • Measured variable: peracetic acid, without cross-sensitivity to the accompanying chemical, hydrogen peroxide
    • Minimal dependence on flow, fewer faults caused by substances in the water and films of dirt as the measuring electrodes are protected by a diaphragm
    • Sensitive measuring range from 0.5 mg/l due to potentiometric 3 electrode system
    • Convenient installation, owing to built-in measuring transducer and plug-in connection of the signal cable
    Measured variablePeracetic acid
