  • Page 6: Instrument Overview

    6 MW160 Bench Meter 2. INSTRUMENT OVERVIEW MW160 is a compact and versatile bench meter that can measure up to four different parameters — pH, ORP, ISE (directly in ppm) and temperature. The main operating modes are setup, calibration, measurement and logging. pH calibration can be performed in up to 3 points (using a selection of 7 standard calibration buffers), to improve measurement reliability, even when testing samples with wide differences in pH.
