If you own a water purifier that uses a reverse osmosis membrane, the only way to check its working correctly is to use a TDS (Total Dissolved Solids) tester. Similarly, the only way to test water quality in your pool, spa or aquarium is to use a TDS meter such as this pen-style tester which also measure temperature.

Essential For:

• Water purifiers and filters
• Hydroponics
• Aquariums
• Food and drink quality monitoring in cafes and restaurants
• Pools and spas

TDS is the total weight of all solids (minerals, salts and metals) dissolved in the water and the lower the TDS level is, the purer the water is. If it's drinking water - the more efficiently your body is hydrated by it, but the higher the TDS levels, the greater the probability of there being harmful contaminants in it.

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