SHELTON, CONN.—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 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 meter:
• The FM-801 may be used for continuous monitoring, and/or for 30-minute spot checks.
• The sensor cartridges are reusable; up to 1,000 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, five 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.
