The pH Meter / pH Tester PCE-DOM 20 is a measuring device to determine the oxygen content both in liquids and in the ambient air. With this pH Meter / pH Tester, water analyzes can be carried out on the oxygen content in a very short time and, with the integrated temperature sensor, the pH Meter / pH Tester is able to carry out automatic temperature compensation. As a result, the pH Meter / pH Tester is also used for analyzing the oxygen content of lakes or streams, as strong temperature fluctuations can occur here, which falsify the measurement result. This pH Meter / pH Tester is also used, for example, in fish farming.
Before the initial start-up, the sensors on the oxygen measuring device are initially dry. In order to carry out a measurement, the sensors of the oxygen measuring device must be provided with the electrolyte supplied. Even if the membrane is damaged, it can be replaced with the oxygen measuring device in just a few steps. This ensures that the oxygen measuring device is ready for use again within a very short time.
