Sensoface provides information on the electrode condi-

tion. The asymmetry potential (zero), slope and

response time during calibration are evaluated. The

three Sensoface indicators provide the user with infor-

mation about wear and required maintenance of the

sensor.

Note: When measuring with DURAFET electrodes,

Sensocheck is not active.
