Multi-Sensor Air Quality Monitors
“Tongdy" multi-sensor monitors provide prodessional air quality data. These monitors are used to simultaneously collect air data including PM2.5 PM10、CO2、TVOC、CO、HCHO、light, noise, temperature, and humidity, with providing options of RS485, WiFi, Ethernet, 4G, and LoraWAN interfaces, as well as data logger. By flexibly integrating multiple sensors into a single unit, and performing environmental compensation on measurement data, Tongdy’s commercial grade air quality monitors provide comprehensive and reliable environmental monitoring, enabling users with precise insights into air quality for informed decision-making. Tongdy provides indoor air quality monitors, in-duct air quality monitors and outdoor air quality monitors. They are all high-quality products which have been used well in over 100 commercial buildings so far.
Carbon Dioxide Monitor / Controller
Since 2009 until now Tongdy has supplied over 20 series advanced carbon dioxide monitors and controllers tailored for HVAC systems, Building Management Systems (BMS), and green buildings. Tongdy’s carbon dioxide products cover almost all CO2 monitoring and control, with options of temperature, humidity and TVOC. These products deliver professional and intelligent air quality monitoring solutions, especially have strong on-site programmable functins to meet more applications. With the most reliable and accurate data, Tongdy’s CO2 products empower smart building managers to make informed decisions, enhancing both operational efficiency and environmental sustainability.
Ozone / CO / TVOC / PM2.5 Monitors and Controllers
Tongdy’s advanced gas monitoring solutions are designed for targeted, cost-effective detection and control of specific gases. With a focus on a single gas including carbon monoxide, ozone, TVOC and PM2.5, our monitors and controllers are ideally suited for these similar applications, such as ventilation systems, storage warehouses, parking lots, and disinfection processes. From 2012 to 2023, we have developed and sold plentiful single gas products including transmitters, monitors and controllers. We also provide tailored product to meet your specific requirements, providing reliable and precise readings to enhance safety and efficiency of your systems.
Temperature and Humidity Controller / Transmitter
Tongdy offers a lot of special temperature and humidity controllers and transmitters for HVAC, BMS systems. VAV room thermostats, floor heating multi-stage controller, dew-proof humidity controller and controllers of temp.&RH with up to 4 relays outputs are provided. In addition to our very diversity range of existing on-wall and in-duct products, we are also skilled in accurately understanding user needs, proposing reasonable solutions, and customizing temperature and humidity products for customers.
