Descrição

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.
