Ermenrich Wett QT20 Water Quality Tester

The Ermenrich Wett QT20 Water Quality Tester is a compact and functional tool that is used to test water from a variety of sources: flow filters, wells, boreholes, household jugs, taps, or aquariums. This tool is suitable for professional applications such as industrial plants, public swimming pools, and fish farms. The tester measures 4 water characteristics: acidity, mineralization/hardness, electrical conductivity, and temperature. Testing requires the immersion of the electrode in water. The measurement result is displayed on the easy-to-read backlit LCD screen. Water acidity is determined in the range of 0–14pH with an error of ±0.05pH. Mineralization/hardness/salt content: in the range of 0–200,000ppm (mg/l) or 10.1–200ppt (g/l). Electrical conductivity: from 1 to 199990μS/cm (microsiemens). Temperature: from 0°C to +60°C (can be displayed in Celsius or Fahrenheit). The Ermenrich Wett QT20 tester”s capabilities will be sufficient to test the quality of any water: both ideal for drinking (0–50ppm) and critically hazardous (>1000ppm). The accuracy of the tester can be improved if you calibrate the device using buffer solutions; sachets with powders for their preparation are included (4.00, 6.86, and 9.18pH). Key features:

• The device is protected from dust and splashes of water according to the IP65 standard
