Belimo Gas Monitors (Air) | Gas monitoring devices | Multi-gas monitor
Applications
Belimo’s gas monitor devices offer an intelligent peer-to-peer communication protocol that gives users unparalleled flexibility to configure and install a complete ventilation control system with only one monitor or dozens operating in multiple ventilation zones.
Accurate and reliable gas monitoring – Indoor parking garages
Exhaust ventilation controlled by Belimo’s gas monitors provides a safe, clean environment and helps to keep energy costs in line. Using carbon monoxide and nitrogen dioxide gas monitors in parking garages offers accurate and reliable exhaust ventilation control where diesel-powered vehicles may also be present. The modular design provides a combined unit with carbon monoxide and nitrogen dioxide sensors within one device, helping to reduce energy costs by measuring emissions and only exhaust-heated or air-conditioned air when needed.
