Portable IAQ Monitor AZ 7755
About this product:
Model AZ 7755 is an easy to use yet highly accurate instrument for determining the carbon dioxide concentration, relative humidity and temperature within the ambient air. At the core of ther AZ 7755 is a long-term stable high-precision CO2 sensor. The backlit LCD shows all three parameters simultaneously and can additionally display dew point and wet-bulb temperature. Conveniently upload data to a computer through the standard USB port. An audible alarm warns when exceeding a pre-defined CO2 threshold which can be adjusted in 100 ppm increments. In addition to the current reading the AZ 7755 can also provide average values, Min/Max, TWA (time-weighted average) and STEL (short-term exposure limits).
Features:
- NDIR technology CO2 sensor - low drift and stable
