Features & Applications:
This Alnor indoor ait quality carbon dioxide meter is the ideal tool for investigating indoor air quality and performing thermal comfort studies. It simultaneously measure and data log multiple parameters: carbon dioxide (CO2), temperature, humidity, and calculates dew point, wet bulb temperature, and % outside air. Ideal applications include investigating indoor air quality, performing thermal comfort studies, checking ventilation systems and conducting IAQ evaluations.
Features:
- Stable NDIR sensor to monitor CO2
- Displays humidity as %RH, dew point, and wet bulb
- Measures temperature
- Calculates % outside air from CO2 or temperature
- Manual or continuous data logging
- Stores 12,700+ sets of downloadable readings with time and date stamp
- Includes LogDat2™ software and interface cable to download to a PC
Includes:
- Instrument
- hard carrying case
- (4) AA alkaline batteries
- calibration collar
- operation and service manual
- NIST calibration certificate
- downloading software and computer cable
