Product Detail
7 inch LCD displayof CO2+ CO2 average (+VOC) + temp. + %RH,
brightness of LCD automatically adjusted with the help of internal
photosensitive sensor
Introduction
The standard monitor has below two models
Carbon dioxide(CO2)+CO2 average +Temperature+ Humidity (Model:DPM-1003)
üCarbon dioxide(CO2)+CO2 average +VOC +Temperature+ Humidity (Model:DPM-1004)
Two unique extended functions (Optional)
üRF short-distance wireless transmission & reception
üUSB data logging
The product can be worked together with our wireless controller to control a ventilator, air cleaning device, or humidity device, based on the real-time measurements and the presetting values of the monitor.
nApplication
üIn all the areas where real time monitoring of indoor air quality such as residence, offices, kindergartens, classrooms in schools, hospitals, shopping malls, restaurants, cinemas and other open areas.
üIndicating and alarm for poor ventilation.
üSound alarm for high concentration to avoid poisoning
üUsed to control a ventilator, air cleaner or humidifier/dehumidifier
üDecrease air pollution and cross-infection for relative closed rooms.
üWith the optional RF short distance wireless module inside, it can be connected to the telecom operating platforms, or other systems. Also realize the remote control
üWith the wireless coordinator together, the IAQ monitors can be connected with a PC
üUSB data logging, record measurement data.
nLCD and display
With large 7'' LCD and 16:9 display, it can be hung easily on the wall or placed on the desk.
With the special self-adaptive brightness design, the LCD can be adjusted its brightness itself based on the light of indoor.
Three-color backlit of the LCD displays the clear and intuitionistic measurements of CO2, VOC, and temperature, relative humidity.
The three-color backlit LCD indicates and alarm different air quality levels:
GREEN-for optimal air quality, YELLOW-for moderate air quality, RED-for poor air quality
self-adjusted brightness LCD, selectable 3-color backlit switch mode
üDetection and Displays:
DPM1003: Carbon dioxide (CO2), CO2 average level (in setting time range: 1~24hous), Temperature, Humidity, Clock and Time.
DPM1004: Carbon dioxide (CO2), CO2 average level (in setting time range: 1~24hous), VOC, Temperature, Humidity, Clock and Time.
Wall-mounted or put on the desk.
nMonitoring Focus
üCarbon Dioxide (CO2)
Indoor CO2 level is a universal accepted parameter for the condition of indoor ventilation and air quality.
A time period can be preset from 1 to 24 hours, e.g. 5 hours, then the monitor can display CO2 average level during this period, which provides an objective and true data for the measurement of the air quality in a certain space.
uNon-dispersive infrared (NDIR) CO2 sensor with more than 10-year lifetime
uABC self-calibration technology guarantees reliable CO2 measurement
uCO2 range: 0~2000ppm/0~5000ppm optional
uRapid response, high stability and consistency
üMix Gases (VOC-Volatile organic compound)
VOC emitted from building materials, decoration materials and furniture, includes toluene, ammonia, H2S, formaldehyde and other harmful gases. Its necessary to real time detect these harmful gases. But it’s costly to use the professional instruments to detect each single gas. Also it’s possible to monitor for daily use. These gases exit in air for a long time and their volatilization level are different in different temperature and humidity, the reliability of such detection by a professional instrument for a single gas is very limited.
This multifunction IAQ monitor uses a mix gas sensor. It has high sensitive to kinds of volatile pollutant gases (VOC) such as ammonia, toluene, formaldehyde and cigarette smoke, alcohol, H2S, and carbon monoxide. So it is very suitable to monitor the general indoor air quality in real time and long term. The mix gases sensor responds quickly to any change of the concentration of such gases. Not only you may open windows for fresh air coming but also the monitor can control a ventilator/air-cleaning devise based on the indication and alarm.
uBuilt in the semi-conductor mix gases sensor
u5~7 years life time
uHigh sensitive to volatile gases like ammonia, toluene, formaldehyde, sensitive to cigarette smoke, alcohol, H2S, etc.
uSmall volume, lower consumption
üTemperature and humidity
Switzerland digital temperature/humidity sensor built in with high accuracy and stability. It also has compensation to CO2 and VOC which makes the measurements more accurate by minimizing environmental effects.
nOptional functions
üShort-distance wireless: built-in the optional short distance wireless module which can receive or transmit measurements, connect to a devise for remote control such as a ventilator, dehumidifier/humidifier, air-cleaning and etc. Also more than 120 units IAQ monitors to be connected to a PC via a wireless router.
üData logging: provide the USB data-logger with internal data-logging module, record real-time measurements, preset the sampling interval time, and can record maximum 60 days data if sampling interval time is 1 minute. Using the special software with the USB data logger, the record parameters can be preset and the data in the monitor can be copied to a USB disk and displayed in PC.
