The Landis+Gyr 535-741 Duct Point Temperature Sensor is a thermistor-based device designed for measuring air temperature directly in HVAC ductwork. It carries model identifiers 535-741 and 535741 and specifies a measurement range from 40 °F to 150 °F. As a Landis+Gyr product, it is intended for integration in building automation and HVAC control systems that monitor duct air temperature. This duct point sensor provides a local temperature reading at the point of measurement to support temperature control, monitoring, and system performance in HVAC and building automation applications.
