Descriptions

Real-time collecting indoor air quality data of intelligent buildings/green buildings, also collecting outdoor data or official release data, upload the data to Cloud through monitoring analysis platform. Read and analyze the data using computer or cellphone. Achieve multi-parameter and all-direction real-time monitoring and assessment of indoor air quality, and use it to control building ventilation and air conditioning system, etc.

• 15 years design and production experience of IAQ (indoor air quality) products, long-term export to global markets, guaranteed by powerful strength.
• Sensor modular and silent design, flexible combination, detection up to 7 parameters with high cost and performance ratio.
• Provide a variety of wired and wireless communication interfaces, connect data collection platform and mobile phone, real-time data monitoring and analysis.
• Applied to fresh air systems and online monitoring of indoor air quality.

Features

• 24-hour online real-time online monitooring of indoor air quality, providing a choice of up to 7 parameters.
• PM2.5 & PM10, CO2, TVOC, temperature & humidity, CO / HCHO optional.
• The above sensor modular design allows you to select different monitoring parameters according to the application scenario
• Using own-patented technology, especially the built-in compensation of measuring value of environmental temperature and humidity, to ensure the accuracy and stability of monitoring value in different environments.
• The upgraded version of TVOC with big data operation is suitable for real-time on-line monitoring of TVOC concentration to avoid the impact of other factors leading to jump or deviation of measuring value.
• Silent design, suitable for rooms, personal offices and other noise-sensitive space.
• Two power supply modes: 12~28VDC/18~27VAC or 100~240VAC. The monitor could be connected to the BAS power, or used separately by municipal power supply.
• Three communication interface options are available: Modbus RS485 or RJ45, or WIFI.
• Select the working mode of the halo indicator. The indicator ring can indicate the indoor air quality level or turn it off.
• Mount the monitor on suspended ceiling or wall combining with technology and fashion with ease and simplicity to match with a variety of decorative styles. Monitor air quality evenly through air circulation.
• The special and core mulit-sensor module is inside, which is designed for the commercial grade monitors. The whole sealed case aluminum structure ensures the stability of detection and improves the anti-jamming capability.
