The AQM-102 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 HVAC system performance
verification.
Carbon dioxide (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 (O2) into carbon dioxide (CO2). Although
carbon dioxide is invisible and odorless, increased CO2
levels can cause headaches, drowsiness and a loss of the
ability to concentrate or worse.
SPECIFICATIONS CO2 Measurement Range: 0 to 9999 ppm Accuracy (400 to 5000 ppm): ±30 ppm, + 3% of rdg Resolution: 1 ppm Temperature Range: 0 to 50 °C (32 to 122 °F) Accuracy: ±0.1°C (2 °F) [0 to 50°C (32 to 122°F)] Resolution: 0.1°C (0.1°F) Relative Humidity Range: 0.0 to 80% RH Accuracy: ±3% RH [at 25°C (77°F), from 10 to 80 RH], ±5% RH below 10% Memory Capacity: 32,000 readings Storage Temperature: -40 to 70°C (-40 to 158°F) Interface: USB Dimensions: 110 H x 108 W x 28 mm D (4.33 x 4.25 x 1.10") Weight: 165 g (5.8 oz)
