The Model 8550 and Model 8551 Q-TRAK IAQ monitors measure CO 2, temperature, and relative humidity.

The Q-TRAK has four modes of operation, Survey, LOG 1, LOG 2, and LOG 3. When the Q-TRAK
is first turned on it will be in Survey mode which is used to display real-time readings and to determine statistics such as average, minimum, and maximum readings. LOG 1 mode is used to record individual data points for later analysis using a factory set protocol.  

INCLUDES:

8550 Q-Trak IAQ Monitor with AC Adaptor, Probe Stand, CO2 Calibration Collar, Computer Interface Cable, Manuals in Hard Shell Carrying Case 

Software, calbrations gas etc not included
