? 3-IN-1 WATER QUATLITY TESTER. It can simultaneously test TDS (Total Dissolved Solids), EC (Electrical Conductivity) and temperature ( Celsius and Fahrenheit ) of water. TDS is a key index of water purity. TDS value ( 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.
? EASY OPERATION. To turn on the water tester and to put it in water for several seconds. After reading in LCD screen are stable for 2-3 seconds, you take it out. Default reading in the screen is PPM. To press MODE button continuously, ?s/cm (EC value), ? and ° F appear successively . Without operation for about 90 seconds, it will automatically turn off.
? MULTI USAGES. The water tester meter can test purity of RO/DI water, tap water, aquarium water, and swimming pool water, and nutrient solution concentration in hydroponics. You can also judge whether vegetables or fruits are polluted by testing purity of water in which they are immersed. In outdoor sports or camping, you can judge whether water quality of water source is good by testing its TDS. In travel to other cities or countries, you can test purity of drinking water and tap water by it.
? STRICT OUTGOING INSPECTION. Before every tester leaves our factory, We use them to test four water samples of different concentrations, and then compare readings among meters
and samples to confirm they are high quality. So tester you receive maybe has a little moisture in its probes and protection cover.
? NOTICES. The water tester meter is a perfect portable testing tool of water quality for home, gardening, outdoor sports and travel, but it is not a sophisticated laboratory research instrument. It doesn’t test PH and doesn’t also analyse ingredients in water. Its average reading error is ±2%-±3%.
