Infrared measuring system for CO2 monitors the air qualityAlthough low concentrations of carbon dioxide (CO2) in indoor air are not toxic for persons, they do decisively affect a person's well-being:
Carbon dioxide can make a person feel tired starting from a concentration of 800 ppm!
Since humans exhale carbon dioxide, this value is quickly reached in closed rooms with many people (conference rooms etc.).
With J. Dittrich Elektronic's carbon dioxide detection system, you can control the ventilation/air-conditioning of closed rooms and buildings depending on the number of people in such a way that
- energy consumption remains as low as possible (no windows standing open constantly with the heat turned on) and
- the persons in the room do not become tired prematurely.
| |  | | | For this purpose, J. Dittrich Elektronic developed a new type of infrared measuring system MF420-IR / MF420-IR-LC, which measures carbon dioxide in the ppm range significantly quicker, more accurately and at less cost than conventional infrared systems. MF420-IR / MF420-IR-LC supplies the measured values to a self-monitoring, freely programmable limit monitor (GWZ-S2, GWZ-S4 or GWZ-S6).
The limit monitor continuously displays the measured values and when a certain concentration of carbon dioxide is reached, it triggers a max. 4-step - either visual or, if necessary, acoustic - alarm or subsequent functions such as, for example, step-by-step control of a ventilation/air-conditioning system. Up to max. 6 gas measuring systems can be connected to a limit monitor.
The infrared system can also control an air-conditioning system directly via its 4-20 mA or 0-10 V output.
The network-capable climate guard monitors besides the carbon dioxid concentration also room temperature and relativ humidity. The output of the measured values is digital, using either Ethernet TCP/IP or Modbus RTU protocol.
