Honeywell Commercial C7400S1000 Economizer Enthalpy Sensor

Experience precise control with the Honeywell Commercial C7400S1000 Economizer Enthalpy Sensor, a digital economizer enthalpy sensor designed for outdoor air intake on rooftop HVAC systems. This compact device delivers reliable accuracy (5 percent) to optimize ventilation and energy efficiency in commercial environments.

Built for harsh environments, the sensor operates from -40 to 150 deg F, handles 11 to 89 percent RH, and easily mounts inside the duct for direct outdoor air sensing. At a light 0.58 lb and a slim footprint of 2.17" W x 0.81" D x 4.25" H, it fits even tight control enclosures.

Key specs include a 20K NTC sensor element, flexible connections, and rugged approvals for safety and compliance.
