Indoor Air Quality Detector

Tongdy MSD Transmitter

The Tongdy MSD transmitter can include multiple sensors such as PM2.5, PM10, CO2, TVOC, HCHO, Temperature &  humidity and can monitor these 24 hours a day. The special multi-sensor module is in a sealed cast aluminium structure which protects it from radio interferences and improves the anti-jamming capability. The sensor has various communication interfaces which include, RS485 Modbus, WIFI & RJ45 Ethernet.MSD

TF9

Outdoor Air Quality Detector

Tongdy TF9 Transmitter

The Tongdy TF9 is specially designed for atmospheric ambient air quality monitoring with multiple sensor options. These sensor options include PM2.5, PM10, Ambient Temperature & Humidity, Ozone (O3), Carbon Monoxide (CO), Carbon Dioxide (CO2), TVOC and Atmospheric Pressure. These detectors are specially designed to protect against rain and snow, high & low temperature resistance, UV-resistant and solar radiation hoods. The sensor has various communication interface options which include RS485, WIFI, RJ45 and 4G Communication.

The new MyTongdy.com data platform is designed to support the latest indoor and outdoor air quality monitors. It offers an online web based platform where the client can monitor the air quality in their buildings. The service also offers Android & IOS applications for ease of use.

//Final CO2 sensor transmitter

CO2 sensor transmitter

Tongdy F12 CO2 transmitter

The Tongdy F12 CO2 transmitter uses a NDIR infrared detector to provide real time readings of the CO2 levels via a 4~20ma or 0-10vdc output. These sensors can be connected to any control device that can effectively measure 0-10vdc or 4~20ma signals. They also have an optional Modbus output for communication to building management systems and PLC’s.

CO2 monitor & controller

Tongdy F2000IAQ CO2 controller

F2000IAQ-CO2 monitor/controller is used to monitor and control, room CO2 levels, as well as room temperature and humidity. It provides one, two or three 0~10vdc analog outputs and up to three dry contact outputs . F2000IAQ-CO2 can be as a programmable logical controller to control CO2 level, temperature or humidity, and also as a transmitter DDC/PLC controller or other automation systems. It provides a RS485 communication interface with an independent address to PC or other control systems.
