Type PAA 2-3E for low concentrations of peracetic acid Peracetic acid is particularly used in the food and beverage industry, but also for disinfection in ... more in the glossary for monitoring peracetic acid Peracetic acid is particularly used in the food and beverage industry, but also for disinfection in ... more in the glossary 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 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 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
