Sensoface
®
was specially designed for monitoring
pH electrodes. Since ORP electrodes have com-
pletely different characteristics, they provoke in-
valid Sensoface
®
displays. Therefore, you should
disable Sensoface
®
for ORP measurements.
Sensoface
®
display can also be degraded when
you use a pH simulator.
