S220 SevenCompact™ pH/Ion Meters
The SevenCompact™ S220 pH/Ion meter is not just an ordinary pH meter, it can also measure ORP and ion-concentration in various units. Switching modes before, during or after measurement is easy requiring just a single keypress.
Pressing a single button – READ or CAL – starts a measurement or calibration, with three options for endpointing. With a timed endpoint the analysis endpoints after a pre-defined time interval. It can also be endpointed manually or the instrument can automatically endpoint according to one of three stability criterion: fast, normal or strict.
