Optional Sensors for use with EGM-5
Internal Sensors and WiFi
The O
2
and H
2
O sensors are built into the EGM-5 enclosure.
O
2
Sensor
An optional electrochemical O
2
sensor can be used with the EGM-5 for measurement of oxygen in
addition to CO
2
.
• Range: 0-100%
• Response Time: ≤ 15 seconds at 23 ± 2
o
C
• Linearity: ± 1.0% of full scale
The O
2
sensor is mounted into a manifold located inside the enclosure and is fitted in-line to sample the
incoming gas stream. Recalibration should not be necessary and based on our experience with this
sensor it should have a working life of approximately 4-5 years.
H
2
O Sensor
An optional solid state H
2
O sensor can be used with the EGM-5 for measurement of H
2
O in addition to
CO
2
.
• Range: 0-Dewpoint (mb)
• Accuracy: < 2% RH
The humidity sensor is mounted into a manifold located inside the enclosure and is fitted in-line to sample
the incoming gas stream. Readings are displayed and recorded in absolute vapor pressure (mb).
Recalibration of this sensor is not necessary.
WiFi
Optional WiFi is available for use with the EGM-5. Refer to Wireless on page 96 for more information.
