A new type of peracetic acid sensor from ProMinent Fluid Controls, the Dulcotest PAA 1, is ideally suited to the food, pharmaceuticals and cosmetics industries.

It is characterised by its dirt and surfactant resistant properties and can be easily integrated with the controller unit.

It operates on-line, is unaffected by media flow and requires minimum maintenance, thus overcoming the problems that impede reliable and continuous measurement and control of peracetic acid levels under practical conditions in the manufacturing process.

Peracetic acid is an environmentally friendly disinfectant and is particularly suitable for aseptic filling, rinsing and CIP (Cleaning in Place) applications.

It reliably disinfects storage tanks, piping systems or product packing drums.

Metering the peracetic acid at the appropriate levels ensures maximum product quality, hygiene and efficiency.

On-line measurement of peracetic acid provides immediate feedback control without the delays associated with sampling and making laboratory measurements.

With complex manufacturing processes often involving several cleaning stages or circuit loops with various flushing agents or active ingredient solution, the PAA1 provides continuous online measurement in order to maintain the correct peracetic acid level in a control circuit.

The sensor also functions selectively even in the presence of hydrogen peroxide and accommodates fluctuations in flow rate and temperature.

Two versions of the Dulcotest PAA 1 are available, offering measuring ranges between 1 and 200 mg/l and between 10 and 2000 mg/l.

These amperometric sensors operate between pH3 and pH8 and are temperature-compensated between 1C and 45C.

The main modules of the peracetic acid measurement station are a DC1 controller, the PAA1 sensor and a flowmeter.

Users benefit from exceptionally simply start-up and maintenance procedures, ease of maintenance, short delivery times and efficient use of chemicals.
