Price on request
The S494PAA sensor is a two-electrode membrane-covered amperometric probe with integrated electronics, which measures the presence of peracetic acid in liquids (equipped with built-in temperature sensor for signal compensation).
It is particularly suitable for the production of beer and drinks in general in the food industry.
For the measurement to take place there must be no interference from the supernatants, and they mustbe absent chlorine, ozone, PES; any sulphites pollute the measurement system.
