Cermet II is the intelligent choice for reliable on-line
measurement of moisture in virtually any gas, across many
applications. Cermet II combines Michell’s Advanced Ceramic
Moisture Sensor and a monitor unit that can be located up
to 1200 m apart (3930 ft). While Cermet II is so simple to
use, it has the fl exibility to be applied to almost any humidity
measurement application. The instrument can display
measurement units in °C or °F dew point, ppmV, lb/mmscf or
g/m3 across the measurement range -100 to +20°C dew point
(-148 to +68°F) at pressures up to 5000 psig. The Cermet II
also can accept a pressure signal from a pressure transmitter
(optional) providing the means of active pressure compensation
for concentration units of measurement.
