March 30, 2012 - Suitable for continuous monitoring and/or 30-minute spot checks, Model FM-801 may be used as independent data logger, with data downloaded to WolfSense PC software. Reusable sensor cartridge, supporting up to 1,000 tests, employs chemical reaction between formaldehyde and -diketone on porous glass. Yellowing that results from reaction is measured via photoelectric photometry with readings ranging from less than 20 ppb to 1 ppm HCHO, without significant cross-sensitivity.

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 -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. The unit 're-zeros' between 30-minute tests allowing for continuous monitoring (unique for this technology), and provides an output for real-time connection to GrayWolf's AdvancedSense(TM) meters, WolfPack(TM) area monitors and to WolfSense(TM) enabled mobile PCs.

Some key facts about this highly innovative meter: The FM-801 may be used for continuous monitoring, and/or for 30-minute spot checks. The sensor cartridges are re-useable; up to 1000 tests per cartridge (at low formaldehyde levels). The base unit may be used as an independent, simple data-logger, with data downloaded to GrayWolf's WolfSense PC software. The FM-801 can also be interfaced to a GrayWolf AdvancedSense meter, WolfPack monitor or WolfSense enabled WIN7 Tablet/Notebook. FM-801 readings are simultaneous to readings from any other sensors connected to the AdvancedSense, WolfPack, or Laptop and are logged into the same data file. Attach audio/photo/video/drawing/text notes to data files for efficient, reliable documentation of surveys. Measurement range is from <20ppb to 1ppm.

The FM-801 formaldehyde meter kit is supplied with a mini-tripod, 5 sensor cartridges, a set of alkaline batteries, AC adapter, WolfSense PC data transfer/reporting software (on CD-ROM or USB key), a USB download cable and a hard-shell carrying case.
