The IAQ Observer is a small, secure, easy-to-use indoor air quality monitor available for rent. Weighing less than one pound, it offers tamper-proof testing with key-locked on/off controls and secure lock and cable. Designed for unattended monitoring, data can be easily retrieved through a secure Web site or disk. The time-consuming task of learning to operate the instrument and calibration is not necessary, since programming is included.
