If you own a water cooler or filter, or other water purification system the only way you will know if its working correctly is to use a TDS (Total Dissolved Solids) tester.

This slim line pen style TDS meter enables you to do so. The TDS is the total weight of all solids (minerals, salts and metals) that are dissolved in the water and the lower the TDS level is, the purer the water is and the more efficiently your body is hydrated by it. The higher the TDS levels, the greater the probability of there being harmful contaminants in it.

If you drink filtered water and you value you and your families health then it makes sense to test the water you are drinking and if the TDS levels are too high then this is a sign that your reverse osmosis membrane needs changing.

The TDS tester couldnt be simpler to use. Powered by two 1.5V batteries the easy-to-read LCD display gives you all the information you need to decide whether you need to change your RO membrane.
