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 eliminates interference caused by turbidity or colouration
- 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
Technical Details
- Measuring range, type PAA 1-mA-200ppm: 0 – 200 ppm
- Measuring range, type PAA 1-mA-2000ppm: 0 – 2,000 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

PAA 1-mA-200 ppm | 1…200 mg/l | 1022506 |
PAA 1-mA-2000 ppm | 10…2,000 mg/l | 1022507 |
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-mA
Sensor for measuring even low concentrations of peracetic acid 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
- Low dependence on flow, reduced faults caused by substances in the water and films of dirt, thanks to a diaphragm protecting the measuring electrodes
- Sensitive measuring range from 0.5 mg/l provided by potentiometric system containing 3 electrodes
- An integrated transmitter and the signal cable’s plug-in connector make for an easy installation
