SECTION 1
General Description
The Model IAQ50 measures Carbon 
Dioxide (CO
2
) level, temperature and
relative humidity, and calculates dew 
point and wet bulb. It also calculates the 
percentage of outside (make up) air in a 
given indoor space, using CO
2
levels, or
temperature. The instrument will deter-
mine statistics and recall individual data 
points for up to 255 test IDs. The Model 
IAQ50 will retain data even after it is 
turned off. 
 
The IAQ50 ships in a soft-sided carrying 
case that holds the meter and probe, a 
probe stand, and calibration collar. There 
is space in the case for an optional Micro-
Printer and charger. The instrument ships 
with batteries (which are not installed), a 
calibration sheet, and this Owner’s 
Manual.
