engine is a pre-calibrated
infrared sensor, and associated signal processing microprocessor
designed for easy integration into other microprocessor based controls
and equipment. The device can provide a voltage or digital output
and is configurable by the user via software and a serial interface.
This module uses the same optical sensor used in many AirTest
products that features a self-calibration algorithm, and an
unique extended optical path length to ensure enhanced stability
and long term performance. The patented folded path length design
of the oval optical bench allows for sampling path lengths of
3" to 14" in a 2" X 2" footprint.
Optical path lengths can be optimized to the desired measurement range
and accuracy required. ISO-9001 manufactured. Platforms available
to measure in ppm or % CO2 ranges.
