CO2 Detector_CDS2000 series

CO2 Detector_CDS2000 series

Description

[Carbon Dioxide(CO2), Carbon Monixide(CO), Particulate Matter(PM), Volatile Organic Compounds(VOCs), Temperature, Humidity]

CDS2000 is compact and easy-to-install IAQ(Indoor Air Quality) sensor, which is designed for carbon dioxide detecting devices in the air. This series is optimized to be used in specific applications such as building and house ventilation system and air conditioning system, which maintains acceptable levels of CO2 in the space by controlling the amount of fresh outdoor air.

Caution on Use

• 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.
