" PCE-PH20 easy-to-use pH meter for pH determination \/ External pH electrode \/ Recalibratable \/ Waterproof (IP 67)","The pH meter was developed to directly determine the pH in aqueous media or water based solutions. The waterproof pH tester PCE-PH20 is used for the fast and accurate measurement of pH. The practical display makes the pH value on the pH meter easy to read. Due to the waterproof and robust housing (IP 67), the pH value tester can also be used under difficult conditions. A recalibration always guarantees optimum accuracy and is very easy to perform using the optionally available calibration kits (automatic calibration function without calibration screws - to be performed only via the keyboard).Water quality in aquariums is extremely important for the living organisms that inhabit it. Slight changes in pH level and temperature may lead to aggravating results and even death of the fishes or reptiles in the water tank. Therefore, application of the appropriate pH meter is required. The ecosystem in the aquarium must be as much similar to the natural conditions as possible. So, the measurements should be regular and provide accurate result.Depending on the purpose of creating an aquarium, commercial, scientific (experimental and laboratory tests), decorative, the most desirable pH level should be maintained to provide correct living conditions for the fishes and other possible organisms there. Modern devices are often portable and easy-to-use instruments which help to monitor the changes in the pH level during the day or from day to day etc. The glass electrodes have long service life and due to a high level of precision and wide measurement range, it is possible to apply the meter often and detect the slightest deviations. For this type of measurements, the presence of the temperature sensor is very important, since the temperature change may occur within one aquarium, and it should be detected at once."
