Outer carton test Strips 290471 - 48pcs

With the EXIT test strips for pools and spas, you can check the quality of your swimming water. To keep the water clean, we advise you to check the swimming water frequently. Using this 3-in-1 test strips, measure the quality of the water by means of the chlorine content, the pH-level and the total alkalinity of the water. Hold the EXIT test strip completely under the water to determine the quality of the water. After 5 seconds, remove the test strip and hold it horizontally without shaking off the water. You can now compare the colours on the strip with the colours on the packaging. The light colours that appear indicate a shortage, while the darker colours indicate a too great quantity. The test strip let you see whether there is enough or too little chlorine in the water, for example. Once you have a clear picture, you can adjust the quantity of chlorine (release) in the water.
