Ground-Breaking New FM-801 Formaldehyde Meter

Press release date: February 20, 2012

A new portable, continuous measurement formaldehyde (HCHO) meter is now available from GrayWolf.

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="">

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.
