Size: AMT76: (W)x(H)=11.69 x 8.27 inch (297 x 210mm) = A4 Paper Why Monitor CO2? Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air. Features: CO2, RH, Temperature measure mode Excellent for measure IAQ in Public places Ultra low cost CO2 Monitor achieved by New IR-SoC Technology It uses Dual Beam NDIR technology to improve the long term stability Specifications: CO2 Measurement Range 0-3,000ppm display Display Resolution 1ppm@ 0~1,000ppm; 5ppm@ 1,001~2,000ppm; 10ppm@ 2,001~3,000ppm Accuracy 0~2,000ppm: ±70ppm or ±5% of reading, whichever is greater; over 2000ppm: +/-7% Repeatability ±20ppm Temperature Dependence Typ. ±0.2% of reading per °C or ±2ppm per °C, whichever is greater, referenced to 25°C Pressure Dependence 0.13% of reading per mmHg Response Time About 2min for 63% of step change Warm-Up Time <60 seconds="" at="" 22="" c="" span=""> Temperature Temperature Range 0°C to 40°C (32°F to 104°F) display Display Resolution 0.1°C (0.1°F when temperature display is within 100°F) Display Options °C/°F Accuracy ±1°C (±2°F) Response Time 20-30 minutes (case must equalize with environment) RH Measurement Range 20%-90% RH Display Resolution 1%RH Accuracy ±5%RH@23°C Response time <5 min="" for="" 63="" of="" step="" change="" span=""> Operating & Storage Condition Operating Temperature 0°C to 40°C (32°F to 104°F) Humidity Range 0 ~ 95% RH non-condensing Storage Temperature -20°C to 60°C (-4°F to 140°F) Power Supply Power Supply Universal 100~240VAC, 50/60Hz , External Power Adaptor Power Consumption 7 Watts ( Max. ) AMT76 CO2 Meter Hygro-Thermometer Hygrometer Thermometer TLEAD ¤ÇÒÁª×é¹ ÍسËÀÙÁÔ à¤Ã×èͧÇÑ´ CO2 à¤Ã×èͧÇÑ´¡êÒ«¤ÒÃìºÍ¹ä´ÍÍ¡ä«´ì
