GenII logger. AQ211 is a comprehensive portable
air quality monitor for primarily indoor use. For
outdoor use a secondary enclosure (type
WBT/AQ) must be used - P.O.A, refer to Eltek.
The compact monitor is normally AC mains
powered. A built-in Li-ion rechargeable back-up
battery is included.
The internal sensors are:
1 x CO
2
1 x CO
1 x NO
2
1 x VOC
3 x Particulate sizes
1 x Temperature within the enclosure
1 x case-mounted RH and
temperature sensor
2 x auxiliary electrode voltages
The particulate sensing module incorporates a
fan unit to control a continuous volume of air for
sampling.
The robust polycarbonate enclosure is fitted with
left hand side ventilation (exhaust) apertures. The
ventilation holes should never be obscured -
doing so can affect the measured values from the
various sensors.
The unit should be located in a cool, dry, non-
0/5000ppm

- Page 3 Principle of operation: Sensors are read sequentially, at a frequency up to 30 seconds and the resulting values are stored. These values are logged and optionally uploaded via an LTE connection. Note that the CO sensor value is measured as an average of 10 measurements in a 120 second period.
