10. Water TDS Meter, Digital Water Quality Tester for Drinking Water, Tap Water and etc.
Feature
- √ WATER QUATLITY TESTER. The tester tests water purity, namely its TDS value ( PPM ). PPM means how many milligrams of solids dissolved in one litre of water, i.e, concentration of all dissolved solids in water. Higher water purity is, smaller PPM is. Notice: it dosen’t tell ph value
- √ EASY OPERATION. Just turn on TDS meter and stir water gently, then stabilized readings will be automatically locked on LCD screen in seconds. And without operation for about 2 minutes, the TDS meter will shut off automatically.
- √ MULTI USAGES. The water meter tests water purity to confirm it is healthy. To monitor whether various water purifiers or filters work rightly, and whether your tap water is up to your local standard, etc.
- √ STRICT OUTGOING INSPECTION. Before every tester leaves our factory, We use it to test four different water samples, and then compare their TDS readings to confirm its accuracy. So the tester you receive maybe has a little moisture in its probes and protection cover.
- √ NOTICES.The meter doesn’t test PH, and doesn’t also analyse water ingredients . It is not a sophisticated laboratory research instrument, but a practical tool of testing water purity for your home. Its average reading error is ±2%-±3%.
