Indoor air quality (IAQ) device to measure carbon dioxide (CO2) concentration, air temperature (degrees C or F), and relative humidity with dew point and wet bulb indicators to diagnose building health, and identify sick building syndrome
Choice of desktop setup, or wall mount attachment
Programmable, audible (80db) and visible alarm for CO2 level indication
Simultaneous LCD display of CO2 (ppm) concentration, air temperature (degrees C or F), and % relative humidity
Stable non-dispersive infrared (ndIR) sensor for CO2 detection
The Supco IAQ50 indoor air quality monitor is a wall-mounted or desktop device that simultaneously displays carbon
dioxide (CO2/ppm) concentration, temperature (degrees C or F), and % relative humidity, has an internal non-dispersive
infrared (ndIR) sensor, and a programmable, audible, and visible CO2 concentration alarm. An indoor air quality (IAQ)
monitor is used for diagnostics, to identify CO2 concentration levels in sick building syndrome, and for continuous
monitoring of residential, and professional environments, such as warehouses, restaurants, garages, and greenhouses.
This IAQ monitor has an LCD display to simultaneously show CO2 concentration, air temperature, and % relative humidity.
The device warms up in 30 seconds. Its time-weighted average (TWA) is 8 hours, and its short-term exposure limit (STEL)
is 15 minutes weighted average. The device emits an audible beep of 80 decibels that can be manually stopped, and the
beep automatically stops when the CO2 reading falls below the lower limit. It is factory-calibrated at 400ppm CO2
concentration for automatic baseline calibration (ABC), and can be manually CO2-calibrated. It has a long time drift
compensation, and minimum/maximum average recall. The non-condensing operational range is +32 to 122 degrees F (0 to 50
degrees C), and it has a -4 to 140 degrees F (-20 to 60 degrees C), non-condensing storage range. An RS-232 port
provides a computer connection. The IAQ50 works with an included 12V adapter, and comes with a 2-year, limited warranty.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to
right; D is depth, the horizontal distance from front to back.
An indoor air quality (IAQ) monitor is used for continuous monitoring of various parameters by professionals and
hobbyists in the home health, aquaculture, agriculture, automotive, and food and beverage industries. Common parameters
include relative % humidity, temperature, and carbon dioxide (CO2) concentration levels. An IAQ monitor can be
handheld, desktop, and wall mount, or a combination of these types.
