AMT - A new laser-based and ultra-portable gas sensor for ...

Abstract. In this work, a new commercially available, laser-based, and ultra-portable formaldehyde (HCHO) gas sensor is characterized, and its usefulness for monitoring HCHO mixing ratios in both indoor and outdoor environments is assessed. Stepped calibrations and intercomparison with well-established laser-induced fluorescence (LIF) instrumentation allow a performance evaluation of the ...

How to calibrate formaldehyde (HCHO) sensor?

The answer / solution to the problem / question documented in this article. Configure the span value of HCHO to 9 ppm in the monitor/docking station. Use 50 ppm CO single-gas (do not use Carbon Monoxide gas from mixed gas cylinders). Proceed with calibration. Use a second bottle of gas if calibrating with AutoRAE 2 for a CO sensor.
