2 Finely tuned for precision and reliability: Sensor technology is above all a matter of trust...and in areas where processes take place under high-tech conditions it is imperative that analysis is completely reliable. The importance of precision and reliability cannot be overemphasised in these areas, and this emphasis must be mirrored in the actual production of the sensors themselves. ProMinent have never underestimated this challenge. Decades of experience and internationally recognised expertise in measuring and control technology has resulted in the continual improvement of manufacturing pro- when preparing the glass for ph sensitive diaphragms. The important factors here are low impedance, minimum acid and alkali errors, temperature resistance and above all, the experience and expertise of a leading manufacturer. nel and machinery approach this challenge with a fresh eye. Another thing to think about and a very recent example the choice of the diaphragm for the reference electrodes determined the measuring accuracy, and thereby the reliability, of the whole process. Production know-how across a complete range of sensors in water-based solutions and for determining total free chlorine diaphragm covered dual and triple electrode probes for the measurement of peracetic acid and H 2 O 2 PT 100/1000 temperature sensor inductive conductivity and conductivity measurement sensors DULCOTEST sensor technology, incorporating ProMinent dosing pumps and measuring and control equipment, is consistently the state of the art for water treatment and process technology single sourced reliability and accuracy! cesses and constant quality control at every stage of manufacture. Accuracy is ensured by our choice of application-specific materials. Our expertise in materials is just one important factor: e.g. High tech glass blowing is of the utmost importance when producing stable glass diaphragms. The electrodes and platinum wires have to be fused, completely free from stresses or hairline cracks. Each day our person- DULCOTEST sensor technology incorporates the following single probes for the measurement of ph and redox diaphragm-covered dual electrode probes for the measurement of chlorine, chlorine dioxide and ozone

3 DULCOTEST Sensor Technology - measuring accuracy moves up to a higher plane! giving you the information you need: every time! ProMinent offers you four reliable measurement systems for water treatment and process technology. Controlled production, precision measurement, simple operation and the minimum of maintenance requirements are all common denominators of: distances they transform the sensor signal into an interference-resistant 4-20 ma signal. A wide range of ph electrodes is offered, to suit all conceivable applications. wire transducers, and once again a wide range of reference electrodes is offered to suit your particular application. The potentiometric sensors tubular case makes them 2. Amperometric analysis Concentrations of chlorine, chlorine dioxide, ozone, hydrogen peroxide and peracetic acid are determined amperometrically, i.e. using a minute (nano-ampere range) current. Potentiometric analysis Amperometric analysis Conductivity measurement Temperature measurement 1. Potentiometric analysis For the potentiometric, i.e. virtually current-free measurement of ph value and redox potential. ph measurement is carried out by a selective glass electrode and a counter electrode. The electrodes are both housed in a compact and easy-to-use single probe. Specially designed two-wire transducers carry out the data transfer, even over large DULCOTEST probes for precise measurement of ph values A platinum electrode for the measurement of redox potential is located, together with the reference electrode, inside the single probe. These are again equipped with twodulcotest sensors for accurate measurement of redox potential uniquely portable and also protects against drying out. When electrodes are spent, simply return them to us and we will take care of the recycling as expected of any manufacturer these days! DULCOTEST chlorine, chlorine dioxide and ozone probes guarantee the highest standard of measurement precision

4 Dual or triple electrode probes are used for this process. These consist of a gold or Electrode housing for safe storage and transport platinum collector and a counter electrode. The triple electrode model contains an additional reference electrode. The electrodes are separated from the measuring medium by a specially designed diaphragm - this is an important requirement to maintain, for instance, a stable zero point and to protect against materials which would otherwise interfere with the readings. Further advantages of the twin wired diaphragmcovered probes include minimal interference, simple installation, minimal maintenance requirements, economical to use, rapid analysis and accurate data transfer. ProMinent produce dual electrode probes for this task, with or without an integrated temperature facility (PT 100/1000). A comprehensive range of inductive and conductive probes, with different cell constants and material variants are available to choose from. You choose the one which suits your process requirements. Conductivity measurement probes are also fitted with specially designed two-wire transducers providing accurate data transfer, even over large distances. 4. Temperature Measurement The ProMinent PT 100/1000 resistance thermometer equipped with twin wire transformers carries out temperature measurements. Modular in-line probe housing for optimum by-pass measurements and everything to go with them! In addition to the probes, we offer a comprehensive package of accessories for the installation, calibration, maintenance and service of the sensors. From modular in-line probe housings for tank bypass installations, through DULCOTEST conductivity measurement probe The ProMinent range covers chlorine probes, ozone, chlorine dioxide, H2O2 and peracetic acid probes each with several different measurement ranges. 3. Conductivity Measurement For measuring electrolytic capacity. DULCOTEST probes enable the continuous measurement of H2O2 and peracetic acid measuring tube combinations and buffer solutions, right up to the transformers: plus flawless service!

5 Quality assurance can never be underestimated! Hard testing - the best preparation for hard practice! Before DULCOTEST sensors are delivered to you they undergo the most strenuous tests. We test every part for correct functioning to ensure that each one is fully operational and conforms to ProMinent standards. Not even the tiniest flaw can go undetected by the tests and examinations we have designed, because you are entitled to complete confidence in the product. Hours and days on the test stand Every ph and redox electrode is tested twice, for example. Once straight after production and then again 14 days later in this way we avoid glassspecific production problems. All important test results e.g. zero point and slope conductance from every DULCOTEST ph sensor is logged and statistically analysed. The amperometric probes are placed under 24 hour stress tests. The objective is to analyse the precision of the measurement under specific application conditions. The reason why every single electrode is so thoroughly tested before delivery is so Electrode container plus recycling box for environmentally-friendly disposal that we can give the uncompromising quality assurance which our customers need: DULCOTEST sensors have to function for long periods within a chain of process components. No ifs or buts! Not the least important variable: the environment As in production technology so in waste disposal environmental aspects are a top priority at ProMinent. Take materials, for instance: in the reference system for ph and redox single probe meters an Ag/AgCl contact is used instead of the poisonous calomel electrode. The most modern production technology saves raw materials on the one hand, and cares for the environment on the other: ph and redox probes are delivered to you in eco-packaging, which comes straight back to us, as we take responsibility for the environmentally-friendly disposal of your spent sensors. Taking responsibility for quality and for environmental sustainability is a claim that you can and should make of ProMinent, beyond merely legal requirements.
