Ground-Breaking New FM-801 Formaldehyde Meter
A new portable, continuous measurement formaldehyde (HCHO) meter is now available from GrayWolf. A reusable sensor cartridge employs the chemical reaction between formaldehyde and ß-diketone on a porous glass. The yellowing that results from this reaction is measured via photoelectric photometry with accurate readings to <20ppb HCHO, without significant cross-sensitivity, making it ideal for Indoor Air Quality (IAQ) applications.
