FM-801 formaldehyde meter

  • The FM-801 may be used for continuous monitoring, and/or for 30-minute spot checks.
  • The FM-801 base unit can also be used as an independent, simple data-logger. Logged data may be downloaded to GrayWolf’s versatile WolfSense PC software.
  • Sensor cartridges may also be used as independent passive samplers which are then checked/displayed via the FM-801 Base Unit.

Formaldemeter

FM-801 formaldehyde meter is a portable, continuous measurement formaldehyde (HCHO) meter 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 from typical background compounds, making it ideal for Indoor Air Quality (IAQ) applications. Tests run in as little as 30 minutes. The unit ‘re-zeros’ between 30 minute tests allowing for continuous monitoring, and provides an output for real-time connection to most GrayWolf platforms.
