เครื่องตรวจจับควัน เตือนภัยเมื่อมีควัน Indoor Air Quality (IAQ) Carbon Dioxide (CO2) Monitor ใช้สำหรับตรวจจับควัน ใช้งานง่าย ใช้ติดตั้งตามพื้นที่ต่างๆ ภายในอาคาร สำนักงาน โรงแรม โรงงานอุตสหกรรม บ้านพักอาศัย คอนโด หอพัก อื่นๆ คุณสมบัติ เครื่องตรวจจับควันThis CO2 monitor will measure CO2 concentration, air (ambient) temperature and relative humidity with visible and audible alarms. Its 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 400ppm. With each breath, human convert oxygen (O2) into carbon dioxide (CO2). Although carbon dioxide is invisible and odorless, an increase CO2-content is apparent because human will noticed increased in fatigue and reduced concentration. It complies with all essential health and safety requirements set out in European Directives (CE marking). Plus, all parts are made and manufactured in Taiwan. Special Features: Super large LCD Simultaneous display of CO2 level, Temperature, Relative Humidity, Calendar (Y/M/D) and Time (clock) Six (6) smiley icons indicating indoor air quality levels (350/450/700/1000/2500/5000ppm) to easily know CO2 concentration Stable NDIR sensor for CO2 detection Selectable High Alarm threshold Selectable ?F and ?C temperature unit Automatic Baseline Calibration (ABC) function Audible warning for high CO2 concentration Dew Point / Wet Bulb Temperature measurement With functions like: MIN/MAX (Maximum & Minimum reading) WBGT (Wet Bulb Global Temperature - great index for checking heat stress) With CE marking, meets Europe's safety, health and environmental requirements Made with durable & reliable materials.
