Ermenrich Wett QT40 Water Quality Tester

The Ermenrich Wett QT40 Water Quality Tester can be used in home, office, and industrial settings to determine the quality of water, its suitability for drinking, and the degree of health hazard. The device is suitable for testing water from a variety of sources: aquariums, swimming pools, jacuzzis, water pipes, wells, natural reservoirs, and hydroponic systems. The tester determines 8 characteristics: pH (acidity), TDS (total dissolved solids), EC (electrical conductivity), salinity, S.G. (specific gravity), ORP (oxidation-reduction potential), hydrogen concentration, and temperature.

The tester determines the acidity/alkalinity in a range of 0–14pH with an error of ±0.05pH; TDS – 0–200000ppm with an error of ±2%; EC – 0–200000µS/cm with an error of ±2%; salinity – 0.01–25% with an error of ±2%; S.G. – 1–1.222; ORP – from 0 to ±1999mV with an error of ±2mV; hydrogen concentration – 0–10000ppb; temperature in the range of 0°C…+60°C. The temperature units can be set to either Celsius or Fahrenheit. Only one water parameter can be tested at a time. The results are displayed on an easy-to-read backlit LCD screen that features 4 digits, current units of measurement, and a charge level indicator.

The Ermenrich Wett QT40 comes complete with special powders for preparing buffer solutions with different pH levels, which are used to calibrate the device.
