Page 3: Measuring Principle
Measuring Principle Measuring Principle The PEROX measuring system is based on amperometric measurements with some special features not found in conventional systems. The small surface area measuring electrode is made of platinum (for hydrogen peroxide measurements) and is covered with a microporous diaphragm cap to make the readings largely independent of the liquid flow conditions. -

Set-Up of the Complete Measuring System Set-Up Examples measuring system in wall-mounted set-up, with automatic temperature correction and flow rate monitoring: ® DULCOMETER D1C controller Measured variable PES/PAA Continuous flow measuring sensor with monitoring facility PT100; for long-distance signal transmission, temperature signal transmitter screwed onto the PT100 sensor type PEROX (4a) -
Page 6: Installation
Installation Mechanical Installation IMPORTANT • When installing the equipment, make quite sure that it is disconnected from the mains voltage! • Interpose a filter in the input feed line if the liquid to be measured is turbid or dirty! • Install a continuous flow sample cooler if the sample temperature is high or subject to large or rapid fluctuations! The PEROX sensor is delivered with a protecting cap to protect the diaphragm and the electrode surface. -
Page 7: Setting Of The Measuring Range
Installation Setting of the Measuring Range The measuring ranges 20/200/2,000 ppm are set via the DIP switch S1 at the transducer PEROX V1. The measuring range is factory-set to 0-200 ppm. The other measuring ranges can be set via the DIP switch positions listed in the table. Hydrogen peroxide (H Switch position S1 Measuring range [ppm]... -
Page 8: Commissioning
Commissioning SAFETY INSTRUCTIONS Disconnect the power supply voltage every time before mounting/removing sensors, signal transmitters and other components. The PEROX signal transmitter must not be disconnected from the PEROX sensor during operation. For the sequence of operating steps on the D1C-controller (settings, calibration, etc.), please consult the ®... -
Page 9: Calibration Intervals
Commissioning / 7 Operation Calibration Intervals The proper calibration intervals depend strongly on the process conditions and the substances actually present in the process water, therefore no generally valid specifications can be given. Under laboratory conditions (pure aqueous solutions of H ), the calibrations intervals are about 3 months. -
Page 10: Polishing The Electrode Surface
Operation Polishing the Electrode Surface - Put a pea-size amount of polishing paste onto a soft (paper) rag. - Press the electrode into the polishing paste and turn it under gentle pressure. - Completely remove the polishing paste from the electrode and sensor shaft by rinsing under lukewarm running water. -
