The HHAQ-108 is ideal for
measuring levels of gaseous
formaldehyde (HCHO) as part
of a workplace indoor air quality
(IAQ) maintenance program,
or to spot-check a residential
environment.
The HHAQ-108 features an
electrochemical sensor which
measures real-time formaldehyde
gas concentration with accuracy
and resolution that meet U.S.
National Institute for Occupational
Safety and Health’s (NIOSH’s)
acceptance criteria. It also tracks,
calculates and displays three
cumulative formaldehyde gas
metrics: 8-hour TWA
(time-weighted average), 1-hour
average, and 15-minute STEL
(short-term exposure limit). The
device is also equipped with a
tripod mount fitting for hands
free monitoring.
