FP-31 Portable Formaldehyde Gas Detector

The portable formaldehyde gas detector model FP-31 is a precision gas analyser which measures gases in the ppm range using photoelectric photometry method with chlorimetric detection tabs. This device is a highly sensitive portable instrument with an easy to read LCD display. The unit is capable of detecting very low levels of formaldehyde, in order to confirm if an area contains safe breathing levels. There are no known interfering gases, as shown on the chart on the reverse side of this sheet.

The inbuilt micro processor controlled sample pump of the FP-31 draws the sample over the tab giving you a direct digital readout. The inbuilt data logger will store up to 99 readings that can be viewed on the display or downloaded on to a PC. The FP-31 is designed to monitor formaldehyde below the World Health Organisation level of 0.08ppm (based on an average reading over 30 minutes with a resolution of 0.005ppm). There are two ranges available for this model.

The portable formaldehyde gas detector FP-31 uses a photoelectric photometry method which utilises colorimetric tablets for detection. A tablet in placed into the instrument, and then a room air sample is pumped onto the tablet for either a 15 minute or a 30 minute period. If formaldehyde is present, it will cause the chemically impregnated tablet surface to darken or stain. The magnitude of the stain directly correlates to the level of formaldehyde in the air. The stain darkness is read by an optical sensor in the portable formaldehyde gas detector model FP-31, and then the instrument calculates the formaldehyde concentration. The portable formaldehyde gas detector model FP-31 then has a direct readout of the formaldehyde measurement on an easy to read LCD display. The unit is capable of detecting very low levels of formaldehyde, in order to confirm if an area contains safe breathing levels. There are no known interfering gases, as shown on the chart on the reverse side of this sheet.
