Multifunction IAQ Monitor

The standard monitor has below two models

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 CO_2, 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

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.
