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, long life 12V air sampling pump
Gas Flow Rate
200-500 cc/min (280-340 cc/min is optimal). An internal, electronic flow
sensor monitors flow rate.
Terminal Block
System power, analog, digital and current (4-20mA) outputs and sensor
inputs are available from the 22 pin terminal block
Analog Output
0-2.5V (CO

range selectable) and 4-20mA
Digital Output
RS232 and USB
Air Filter & Water Trap
An external water trap and internal hydrophobic filter are used to protect
analyzer from water.
Alarm
Visual and audible alarm/warnings. 2 relay contacts (Alarm1 and Alarm2)
