Ground-Breaking New Formaldehyde Meter

A new portable, continuous measurement formaldehyde (HCHO) meter is now available from GrayWolf (USA). 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. 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 meters, WolfPack area monitors and to WolfSense 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.
