The Apera Instruments EC20 tester is simply the most reliable conductivity (EC) tester with the best value for all kinds of regular EC testing, such as hydroponics, education, tap/drinking water, swimming pool, water treatment, etc. Up to 2 points of Auto Calibration with buffer recognition and 0 to 50˚C Auto Temperature Compensation (ATC), ±1% F.S, 0.5˚C accuracy with measuring range of 0-200.0 µS/cm, 0-2000 µS/cm, 0-20.00 mS/cm, 0-50.0˚C.
The BPB (Brush-Resistant Platinum Black) sensor adopts our special processing technology, which minimizes electrode polarization, expands measuring range, and increases the firmness of the electrode, hence ensuring a much higher accuracy and consistency in a wide-range EC measurement than traditional stainless steel electrodes, and is easy to clean.
Large clear 180˚ viewing angle screen with temp./EC value dual display and indications of completed auto calibrations and stable readings. Great functions to make your testing experience a lot easier: 3-point auto calibration with auto buffer recognition, 0 to 50˚C auto temp. compensation. Self-diagnosis with out-of-range and low battery warning, and incorrect calibration reminder.
