RKI FP-31 Formaldehyde Monitor soil testing Calibration CapThe RKI FP 31 is a compact, sample draw formaldehyde monitor built for fast, on site indoor air quality testing. Using a photoelectric colorimetric method with disposable detector tablets, it reads formaldehyde concentration over a 15 minute (01. 0 ppm) or 30 minute (00. 4 ppm) averaging period with no warm up delay before sampling. Because its optical measurement isn't thrown off by common cross interferents like toluene, benzene, carbon monoxide,
