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

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
