Vaisala CARBOCAP GMW86P - Product Overview; Introduction to GMW80 Series

2 PRODUCT OVERVIEW
Introduction to GMW80 Series
Vaisala GMW80 series CARBOCAP® carbon dioxide, humidity, and
temperature transmitters are wall-mount transmitters designed to fulfill the needs
for CO
2
measurements in standard demand controlled ventilation applications.
The CO
2
measurement is based on a new generation CARBOCAP® sensor,
which uses a novel, silicon-based microchip emitter instead of an incandescent
light bulb. The internal reference in the CO
2
sensor guarantees the best stability
and operation also in constantly occupied buildings without frequent
readjustments.
CARBOCAP® sensors give correct CO
2
measurements immediately when
powered on. As they have a built-in reference measurement they do not need a
lengthy learning phase before the measured values are correct. Proper
operation can be verified immediately after snapping on the device cover.
All GMW80 series transmitters measure carbon dioxide (CO
2
) and temperature
(T), some models also include relative humidity (RH)measurement as well.
Humidity measurement utilizes the Vaisala INTERCAP® sensor.
Transmitter models and their features are listed in Transmitter Models on the
