FM-801

formaldehyde meter, Monitor

Formaldehyde (HCHO) Measurement to very low levels of detection

The FM-801 formaldehyde meter, for continuous or portable measurement, has a range from 10ppb (parts per billion) to 1000ppb, with actual limits of detection down to <5ppb (below the display value). Display your readings in ppb or µg/m3 HCHO. These very low levels of detection are essential for Indoor Air Quality (IAQ) measurement of Formaldehyde, and are typically not achieved by alternative continuous measurement technology.

Formaldehyde Meter

Formaldehyde Testing; continuous monitoring or spot checks

FM-801 formaldehyde meter is a portable, continuous measurement formaldehyde (HCHO) meter available from GrayWolf. Tests run in as little as 30 minutes. The unit ‘re-zeros’ between 30 minute tests allowing for continuous monitoring/data-logging, and provides an output for real-time connection to most GrayWolf platforms.

Some key facts about this ground-breaking meter:

  • The FM-801 may be used for continuous monitoring, and/or for 30-minute spot checks.
  • The FM-801 can be interfaced to a GrayWolf AdvancedSense meter, WolfPack monitor or WIN7/8 Tablet/Notebook. FM-801 readings are simultaneous to readings from any other sensors connected to the AdvancedSense, WolfPack, Tablet or Laptop, logged into the same data file. Attach audio/photo/video/drawing/text notes to data files for efficient, reliable documentation of environmental surveys.
  • When connected to a GrayWolf meter, readings may optionally be accessed via WiFi, and alerts can be sent via text and e-mail.
  • 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 (included), and presented in reports generated with GrayWolf’s optional WolfSense ARG automated reporting.
  • Sensor cartridges may also be used as independent passive samplers which are then checked/displayed via the FM-801 Base Unit.

Photoelectric Photometry

A reusable sensor cartridge employs the chemical reaction between formaldehyde and ß-diketone in 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 IAQ applications.
