The Anton IAQ8494 is a handheld carbon dioxide (CO2) meter for indoor air quality assessment, ventilation testing and flueless gas appliance safety checks. It is not a carbon monoxide (CO) detector — CO2 build-up is a different indicator, showing when ventilation isn't adequately clearing exhaled or combustion gases from a space, which in turn confirms whether flueless appliances are operating safely.
It measures CO2 across a 0 to 9,999 ppm range with 2 ppm resolution using an NDIR (non-dispersive infrared) sensor, a technology chosen for its stability and long service life — the sensor has an anticipated lifespan of up to 15 years, considerably longer than typical electrochemical CO2 sensors. A maximum alarm threshold is set at 9,900 ppm, with the adjustable audible alarm able to be set lower to match the specific assessment.
The instrument records minimum and maximum CO2 levels during a session and calculates time-weighted averages, which is the format needed for occupational exposure assessments and compliance reporting. Fresh air correction allows the baseline calibration to be adjusted manually, and an RS232 interface allows measurement data to be transferred to a PC for analysis and record-keeping. Ambient temperature is also measured, from -10°C to +60°C with ±0.6°C accuracy.
It's BS8494 compliant across the 10-60°C range specified by the standard, and comes with a rugged blow-moulded carry case, DC mains adaptor and 4 x AA batteries.
Key Features & Benefits
BS8494 compliance makes this the right documented instrument for checking flueless gas appliances are operating safely, rather than relying on a general-purpose CO2 meter without that certification. The NDIR sensor's anticipated 15-year lifespan is considerably longer than typical electrochemical alternatives, making it a longer-term investment rather than an instrument that needs replacing every few years. Time-weighted average calculation gives the data format needed for occupational exposure and compliance reporting, and the RS232 interface allows records to be transferred directly to a PC rather than transcribed manually from the display.
