SD-622 Duct Smoke Detector
Sontay Duct Smoke Detector
Non-dispersive infrared sensor for measuring CO2 concentrations and utilising microprocessor based electronics, they offer long-term stability and accuracy.
Using a non-dispersive infrared sensor for measuring CO2 concentrations and utilising microprocessor based electronics, they offer long-term stability and accuracy. Transmitters are available with active temperature and RH outputs, as well as a directly connected passive resistive temperature output along with other passive outputs. The -UN has a single output which automatically determines whether to run in current or voltage mode, no more jumpers or switches to worry about. The sensor can be used to ensure adequate ventilation while maximizing energy savings by ventilating at the optimum level, making these ideal for all types of ventilation in commercial buildings, industrial plants, laboratories and public spaces, such as schools.
