AQM-102

AQM-102 carbon dioxide monitor and data logger is designed to measure CO2 concentration, air temperature and relative humidity with visible and audible alarms. This CO2 monitor is an ideal instrument for indoor air quality (IAQ) diagnosis and local exhaust ventilation (LEV) system performance verification. CO2 is a gaseous component of the earth’s atmosphere. The concentration of CO2 in natural ambient air is about 0.04% or 400 ppm. With each breath, humans convert oxygen into CO2. Although carbon dioxide is invisible and odourless, increased CO2 levels can cause headaches, drowsiness and a loss of the ability to concentrate or worse. The Control of Substances Hazardous to Health (COSHH) Regulations 2002 impose a legal requirement for the workplace control of exposure to Carbon dioxide, by reference to Table 1 of EH40/2005 Workplace Exposure Limits. The Long-term exposure limit for Carbon dioxide as listed in EH40 is 5,000 ppm or 9,150 mg/m³ (8 hour TWA reference period).

• Large LCD displays CO2 level, temperature, relative humidity, calendar (Y/M/D) and time
• Six (6) smiley icons indicate indoor air quality levels at (350/450/700/1000/2500/5000ppm)
• Stable Ndir Sensor for CO2 Detection
• Programmable high alarm
• Manual 400ppm calibration
• Audible/visible LED warning for high CO2 concentration
• Heat index/Wbgt temperature calculation
