Ion 700 meter measures pH, mV, relative mV, and temperature while adding ion measurement capabilities. Ion concentration is directly read in ppm for easy use. Verify electrode operation while taking measurements with the dual ppm and mV display. Up to three ion-concentration standards (choose from 0.1, 1.0, 10.0, 100.0, or 1000.0 ppm) may be calibrated.

The easy-to-use, microprocessor-based meter features HOLD, ATC, recorder output, and electrode diagnostics. 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 convenient pull-out quick reference card keeps procedures handy at all times. The large, dual-display LCD provides excellent visibility—even from a distance. Meter accepts pH, ORP, or ion-selective electrodes with BNC connectors.
