Monitoring the chlorine content in water is a fundamental aspect of water hygiene in clinics and hospitals. Chlorine serves as an effective disinfectant that kills pathogenic microorganisms such as bacteria and viruses, ensuring safe water quality. Accurate monitoring of chlorine levels is crucial to ensure the safety of patients and staff, especially in medical facilities where water is used for a variety of purposes - from cleaning medical equipment to supplying drinking water.
The DPD method for determining chlorine levels provides a reliable and accurate way to measure free chlorine levels in water. This method is particularly popular in clinical water treatment, as it provides fast and accurate results that are necessary to fulfil legal and hygiene requirements. An optimum chlorine content ensures continuous disinfection of the water and prevents pathogens from multiplying in water-bearing systems.
A clean water supply is essential in sensitive areas such as operating theatres, dialysis units and intensive care units. Insufficient chlorine levels can increase the risk of infection, which is why regular checks are essential. The DPD method ensures that the chlorine content is always within the optimum range, guaranteeing reliable disinfection that fulfils the strict requirements of the healthcare sector.

The Testoval Chlor DPD 0.5-4 mg/l is a handy colour comparison test kit for quickly determining the free and total chlorine content in water in the range from 0.5 to 4 mg/l. Within about one minute, you can see how much chlorine is contained in the water. Quickly determine chlorine levels – easily and reliably The test works according to the DPD method. This means that you place a defined amount of water sample in a measuring tube, add the enclosed reagents and compare the resulting colour with the scale included in the delivery. The stronger the colour, the higher the chlorine content. The values 0.5, 1, 1.5, 2, 3 and 4 mg/l can be read directly on the colour scale. Possible uses of the test The test is particularly well suited for reliably checking the chlorine content in water without measuring devices, for example in: Swimming pools and bathing facilities to ensure that the disinfection value is within the optimum range Water treatment or monitoring, when chlorine needs to be checked as an indicator of hygienic water quality As the test works manually by colour comparison, no expensive measuring equipment is required and samples can also be tested on the go.
