The AZ Instrument 7755 is a high-performance, multi-functional handheld IAQ (Indoor Air Quality) monitor designed to provide meticulous analysis of the indoor environment. Utilizing advanced NDIR (Non-Dispersive Infrared) technology, it delivers a triple display of CO2 concentration, ambient temperature, and relative humidity. Beyond basic parameters, the 7755 also calculates Dew Point and Wet Bulb temperatures, making it an indispensable tool for HVAC technicians, industrial hygienists, and environmental researchers.
Engineered for safety and compliance, the device displays critical exposure metrics including the 8-hour TWA (Time Weighted Average) and 15-minute STEL (Short-Term Exposure Limit). Its unique housing design, featuring peripheral ventilation rails, ensures rapid response times by facilitating optimal air circulation to the sensors. With the ability to stream data directly to a PC every 2 seconds via USB, and easy manual calibration for both CO2 and humidity, the AZ Instrument 7755 stands as the definitive professional standard for comprehensive air quality diagnostics and workplace safety monitoring.
