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
Technical Details
- 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
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
