This easy-to-use water-test kit is a compact unit made out of strong plastic, that will probably last for years. There is no risk of dropping glass test tubes in pool areas - with glass shards everywhere!
The tester has a cell on one side to read the pH level, and a cell on the other to read free chlorine level. You simply rinse the cells with clean fresh water, and - holding it upside-down - put your hand under water up to your elbow and then invert the tester to fill it with water.
This is to give a more accurate indication of the chlorine content of the water - as the water in the top region of a pool is beginning to lose its gas content as it escapes to atmosphere.
This comes complete with 20 x DPD No 1 tablets to test free chlorine, 20 x Phenol Red tablets to test pH levels, and full instructions. Simply replenish your supply of test tablets when you need, and this is a quick, cheaper alternative to test strips!
-These tablets are the same as are used for manual tests in swimming pools and leisure centres throughout the UK.
