The multiparameter display of the IAQ50 and IAQ55 provides simultaneous readings for CO2, temperature, and humidity. Utilizing a nondispersive infrared CO2 sensor, each IAQ instrument provides fast, stable measurements for CO2, while the audible (80 db) and visual alarms notify the user when user-programmed alarm thresholds are violated. The IAQ50 is a wall-mounted or desktop monitor, while the IAQ55 provides portable hand-held IAQ measurements. Features include a large triple-function LCD display; min., max., and average recall; long time drift compensation; eight-hour time-weighted average; and 15-minute short-term exposure limit.
