The Vaisala CARBOCAP® Carbon
Dioxide Transmitter Series GMT220 is
designed to measure carbon dioxide
in harsh and humid environments.
The housing is dust- and waterproof
to IP65 standards.
The GMT220 series transmitters
incorporate the advanced Vaisala
CARBOCAP® Sensor. The patented
sensor has unique reference
measurement capabilities. Its critical
parts are made of silicon; this gives
the sensor outstanding stability
over both time and temperature. By
lengthening the calibration intervals,
the user saves both time and money.
Interchangeable probes
The user has a choice of
measurement ranges up to 20%
of CO2. The GMT221 is for higher
concentrations of CO2 and the |
GMT222 for lower concentrations
of CO2. The GMT220 probes are
interchangeable. They can be
removed and reattached or replaced
at any time – without the need for
calibration and adjustment. The
probes can be attached directly to
the transmitter body or, when used
with a cable, installed remotely into
hard-to-reach places or areas with
dangerously high levels of CO2.
The interchangeability of the GMT220
transmitter’s probes truly facilitates
fi eld maintenance.
The end user can carry out fi eld
maintenance without any additional
equipment or heavy and expensive
calibration gas bottles by simply
replacing a probe.
Probes that have been replaced can
be sent to Vaisala for recalibration. |
