The easy-to-use, microprocessor-based WD-35419-11 Eutech pH700 benchtop meter measures pH, mV, relative mV, and temperature. The large, dual-display LCD provides excellent visibility—even from a distance. Automatic temperature compensation (ATC) maintains reading accuracy even with fluctuating temperatures. Five-point pH calibration, with automatic buffer recognition for both USA (pH 1.68, 4.01, 7.00, 10.01, 12.45) and NIST (pH 1.68, 4.01, 6.86, 9.18, 12.45) pH buffers, makes for easy calibration no matter which requirement you need to meet. The WD3541911 Meter features HOLD, ATC, and electrode diagnostics. The convenient pull-out quick reference card keeps procedures handy at all times. Meter accepts any pH or ORP electrodes with a BNC connector. This product includes the pH 700 meter with a double-junction glass pH electrode, ATC probe, and an electrode holder. It has also been certified with NIST-Traceable calibration.
