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.
