GENERAL DESCRIPTION:
The model GVU-CO
2
Carbon dioxide sensor is designed to interface
with a Toxalert Int’l model GVU series control unit. The sensor/trans-
ducer consists of a patented solid state infrared CO
2
monitor housed in
an attractive plastic case. The GVU-CO
2
has a new state-of-the-art
lithium tantalate detector, updated electronics and unique auto-zero
function. This results in very stable calibration and longer trouble-free
operation in the field. The new IR source is more rugged, operated at
10X derated power and has a life expectancy of 10 years. The new lithium
tantalate detector enhances stability, has less ambient temperature sen-
sitivity and faster response time. The GVU-CO
2
has a range of 0 to
2000 ppm with a repeatability of
+
20 ppm. The enclosure has louvers to
allow free passage of air to the sensing cell inside.
