Peracetic Acid Analyzer – PeraSense
Online, continuous Peracetic Acid Analyzers, Peracetic Acid Monitors, Peracetic Acid Meters and Peracetic Acid Controllers make up the PeraSense range which utilizes the very latest and best peracetic acid sensors available in the world today. It is a membraned device which uses no reagents, is extremely stable, and has reduced maintenance and reduced whole life costs.
The PeraSense peracetic acid sensors, which give a peracetic acid measurement in ppm or mg/l, and a range of flow cells, are available with different peracetic acid controllers giving you the same great performance with different communication, display and control options. With the PeraSense range of peracetic acid analyzers, you get everything that you need – and nothing that you don’t.
The PeraSense Peracetic Acid Monitor is used in many applications requiring the measurement of peracetic acid concentration simply for peracetic acid monitoring or peracetic acid dosing control.

Pi’s peracetic acid analyzer is designed to have reduced maintenance, reduced calibration and reduced spares requirements. The PeraSense CH3CO3H analyzers are undeniably the most cost effective CH3CO3H analyzers available. In most situations the PeraSense analyzer is able to control the dosing of CH3CO3H by adjusting flow rates, pump rates, or valve positions automatically to maintain the peracetic acid set-point. Automatic dosing can significantly reduce reagent costs, and increase the level of control.

Pi’s peracetic acid sensors have very low drift rates so how often you calibrate your sensor, depends on the application. Our customers range from people who calibrate once a week to once a month, even to once every six months.
This is dependent on the water quality, but usually every 3-6 months.
This is dependent on the water quality, but usually once a year.
Yes, but only if you are using the sensor at above pH 7. If this is the case, please contact Pi to discuss your application.
Yes, chlorine dioxide and ozone. Contact Pi for more information.
Two years in a cool, dry place.
PVC-U, stainless steel and a hydrophilic membrane.
Pi’s peracetic acid sensors work at a positive voltage all the time. This means that any drift is negligible when compared to the positive operating voltage and therefore, no zero is necessary.
Nothing. Sensors are often affected by temperature, but the PeraSense has a built-in internal thermistor that allows for automatic temperature compensation meaning that you don’t have to worry about variations in temperature.
We recommend using a handheld colorimetric DPD meter. An alternative is the electrochemical test kit, Kemio from Palintest. This is currently proving to be a very popular device.
There are three main factors to think about;
There are three main factors to think about;
- Take the sample from right at the instrument
- If the concentration is changing quickly, do not take a sample
- Use a reliable handheld meter and be sure to follow the instructions
During calibration, the CRONOS® or CRIUS®4.0 controller monitors the stability of the probe signal. If this stability varies by more than 10% during the countdown, then the CRONOS® or CRIUS®4.0 will prevent calibration to prevent errors.
