• Do not use this device for outdoor use. This product is provided only for indoor use.
• Do not use this device for where a building is continuously occupied 24 hours per day, or where there could be significant sources of non-occupant related CO2 such as greenhouses, breweries and other industrial and food processing applications.
• Do not use this device for medical or safety purpose.
• Do not leave or use the device for longtime in a highly-damped place in which humidity is near 95%RH.
• The standard test condition in which the product was tested is 25℃±3℃, 50℃±30%RH. Signal may vary slightly by environment condition.
• This device must abide by the operating temperature/humidity and the storage temperature/humidity.
• Use the product when it is completely fixed and do not use it while it is in motion.
• We do not guarantee the performance of the device in the case of user installation, disassembling and inspection. When installing and inspection is necessary, please contact our technicians.
• NDIR sensor can be influenced by air pressure. It can be used without correction within 300M above the sea level. However, add the output value by +1.0% per 100M height above 300M.
Ex) If the output signal indicates 600ppm at the height of 500M, correct the output value to 630ppm by adding 30(600*0.01*5)ppm.
• Be careful when install and use the product as vibration, shock, and falling can cause a serious damage on the sensor.
