Tongdy , PMD Series In-Duct Air Quality Detector

FEATURES

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.
