• PMD-18 in-duct air quality detector is specially designed for monitoring multi-parameter air quality in air duct, Which is installed in wind duct or return air duct.
• The built-in sensor module uses Tongdy’s patented data algorithm, with enclosed cast aluminium structure. It ensures the stability, air closure and shielding, greatly improves the anti-interference ability.
• Built-in a large air bearing fan, regulate the fan speed automatically, guarantee constant air volume and improve the stability and lifetime in long-term working.
• Special design of pitot tube, instead the air pump mode, adapt to a wider range of wind speeds. To have longer lifetime and no need to change the air pump frequently.
• Easy to clean filter mesh, can be disassembled and used many times
• With temperature and humidity compensation, reduce the impact of environmental change.
• Real-time monitoring parameters: particles (PM2.5 and PM10), carbon dioxide (CO2), TVOC, air temperature and humidity, as well as optional carbon monoxide or formaldehyde,.
• Independently measure the temperature and humidity in the air duct, avoid interference from other sensors and monitoring heating.
• Provides WIFI, RJ45 Ethernet, RS485 Modbus communication interfaces selection. Provide multiple communication protocol choices.
• Connect to the data acquisition/analysis software platform to achieve data storage, data comparison and data analysis.
• Data can be read and displayed on-site with blue tooth or the operation tool.
• Working with MSD indoor air quality monitors together, comprehensively and accurately analyze the air quality. Quantitative assessment of indoor air pollution.
• Working with TF9 series outdoor air environment monitors together to form a partial and complete regional air quality monitoring, analysis and treatment system.
