Readings are automatically corrected for temperature and pressure.
Accuracy
< 1% of span concentration over the calibrated range but limited by the
accuracy of the calibration mixture.
Linearity
< 1% throughout the range
Stability
Auto-zero at regular intervals corrects for sample cell contamination,
source and detector ageing and changes in electronics.
Warm-up Time
Approximately 15 minutes
Sampling Rate
10 Hz. Sample data is averaged and output every 1.0 seconds.
Sampling Pump
Integral, 5V rotary vane air sampling pump
Gas Flow Rate
100-500 cc/min (280-340 cc/min is optimal). An internal, electronic flow
sensor monitors flow rate.
Terminal Block
External 10 pin terminal connector for; +5V, Ground, Analog input, Analog
output, and alarm relays.
Analog Input
0-1.0V
Analog Output
0-2.5V (CO
2
range selectable)
Alarm
2 relay contacts (Alarm1 and Alarm2), Visual and Audible alarm/warnings.
Communications
USB(USB Mini-B) and Optional Wi-Fi
Air Filter
Internal hydrophobic filter is used to protect analyzer from water.
CO

Control
High and low user set points
Data Storage (USB)
USB Flash Drive for data storage
Display
2.7” electronic paper touch display with 264 x 176 pixel resolution
Power Switch
Illuminated On/Off power switch
Internal Battery
7.2 Volt - 8.7Ah (63Whr) Li-Ion battery providing up to 16 hours continuous
operation. If external sensors/accessories are used with the EGM-5 it will
reduce the operation time.
Power Requirements
12 VDC, 3.0A or AC Adapter (included) 100-240 VAC, 50-60 Hz, 1.0A
Power Consumption
Charging Battery: 30W (12V @ 2.5A)
Warm up: 12W (12V @ 1.0A)
Normal operation: 6W (12V @ 0.5A)
Gas Connections
2 Quick disconnect style fittings (inlet and exhaust) for use with 1/8” (.125”)
ID tubing
Operating Temperature
0-50
o
C, non-condensing. External filtration may be required in dirty
environments.
Enclosure
Durable Cast-Urethane and aluminum, IP43 enclosure
Dimensions
215 cm W x 200 cm H 120 cm W (Enclosure only)
Weight
1.6 kg
