Formaldehyde detector FP-31G

The FP-31G formaldehyde meter, for portable 15 or 30 minute test results, has a range from 10ppb (parts per billion) to 1000ppb, with actual limits of detection down to <5ppb (below the display value). Display your readings in ppm HCHO. These very low levels of detection are essential for Indoor Air Quality (IAQ) measurement of Formaldehyde, and are typically not achieved by alternative continuous measurement technology. FP-31G formaldehyde meter is a portable, portable formaldehyde (HCHO) meter available from GrayWolf. Tests run in as little as 15 minutes for the higher 0.01 to 1.00 ppm range, yet only 30 minutes for the lower 0.005 to 0.400ppm IAQ range. Some key facts about this meter: There are no known interfering gases (a significant problem for most other HCHO sensor technologies at low ppb levels). Built-in sample draw pump. There is no warm-up time necessary for the FP-31G, improving efficiency on-site. Insertion and removal of detection (test) tablets is quick and simple. Displayed readings may be manually entered onto a GrayWolf AdvancedSense meter or WolfSense LAP enabled tablet, at the time they are taken, adding those data points to any other parameters being trend logged on the other devices. The FP-31G can also be used as an independent, simple data-logger, storing up to 99 readings. Logged data may be downloaded to complimentary software via an optional cable (USB-IRdA). Photoelectric Photometry An inserted test tablet employs the chemical reaction between formaldehyde and a chemical impregnated in the surface of the tablet. The discoloring that results from this reaction is measured via photoelectric photometry
