HSH—RM3M

Brief Description: The Honeywell HSH-RM3M is a remote-mount humidity and temperature sensor with a 3-meter cable, designed for integration into HVAC, building automation, and environmental monitoring systems. It provides resistive (humidity) and NTC (temperature) outputs, making it compatible with Honeywell and third-party controllers. Key Features: ✔ Dual sensing (humidity + temperature) in one unit ✔ Long cable for flexible installation in ducts, chambers, or confined spaces ✔ Stable & reliable performance for critical climate control ✔ Low drift for long-term accuracy Typical Applications: HVAC systems (air handlers, VAV boxes) Cleanrooms and laboratories Data centers and server rooms Greenhouses and agricultural monitoring
