DULCOTEST Sensors for Peracetic Acid

Graduated measuring ranges 0.02 – 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 wastewater treatment.

Reliable Online Measurement of Peracetic Acid with DULCOTEST Sensors.

DULCOTEST sensors of types PAA 1 and PAA 2-3E are diaphragm-covered amperometric sensors for the selective measurement of peracetic acid. You have the option of two sensor types for applications with different requirements:

Type PAA 1 with extra thick, pore-free diaphragm for average and higher concentrations of peracetic acid for applications in the food and beverage industry.

Type PAA 2-3E for low concentrations of peracetic acid for monitoring peracetic acid limit values in clarification plant processes or for applications in the pharmaceutical industry and medical technology, for example.

Your Benefits

  • Precise amperometric measurement in real-time for efficient process control
  • Amperometric measuring eliminates interference caused by turbidity or discolouration
  • No cross-sensitivity towards hydrogen peroxide
  • 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

Technical Details

  • Type PAA 1: 1 … 200 ppm and 10 … 2,000 ppm
  • Type PAA 2-3E: 0.02 … 2 ppm and 0.2 … 20.0 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 to hydrogen peroxide. For disinfecting contaminated water from washing foodstuffs and from cleaning procedures (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

Note: A mounting kit (order no. 815079) is required for initial fitting of the sensors in the sensor bypass fitting DLG III.

Peracetic acid sensor PAA 2-3E-mA

Sensor for measuring even low concentrations of peracetic acid without cross-sensitivity to hydrogen peroxide even in wastewater (pre-cleaned)

Your Benefits

  • Measured variable: peracetic acid, without cross-sensitivity to the accompanying chemical, hydrogen peroxide
  • Low dependence on flow, reduced faults caused by substances in the water and films of dirt, thanks to a membrane protecting the measuring electrodes
  • Sensitive measuring range from 0..02 mg/l provided by potentiometric system containing 3 electrodes
  • Measured values for monitoring or fast control due to short sensor response time < 30 s
  • An integrated transmitter and the signal cable’s plug-in connector make for an easy installation
