Overview
Enviro Tester well-constructed water quality meter is designed to provide zero oxygen and full scale
calibration. It contains three measurement modes which are continuous measuring, timing measuring,
and balance measuring mode. This device can be used to provide the measurements of the pH, pX, ORP,
ion concentration, conductivity, resistivity, TDS, salinity, dissolved oxygen, saturation, and temperature
at the same time. Moreover, this meter also offers many ion modes such as H+, Ag+, Na+, K+, NH4+, Cl-, F-, NO3-, BF4-, CN-, Cu2+, Pb2+, and Ca2+. The users can define ion modes by themselves if choosing corresponding ion sensors. The instrument is designed to follow the GLP practice and can store 2200 sets of measuring data. Measuring data can be viewed, printed, deleted, or transferred to a PC via an RS-232 and USB interface. Enviro Tester water quality meter also features a 5.7 inch (144.78 mm) large
touch screen with English operating systems that allows users to view current measuring data and the
last calibration data.
