The TSI Q-Track can be used as a hand held battery operated device for surveying, or AC Adapter and used to collect data over time in one area. It monitors Temperature, humidity, CO2, and CO. Works fine and has been in active service. Last factory calibration was in 2003 but tested routinly against another factory calibrated monitors. Company is down sizing and no longer needed.
