The Comet H3531R is the professional 1U rack-mount thermo-hygrometer with Ethernet interface, two relay outputs, three binary inputs, and humidex calculation. Ideal for reliable monitoring in server rooms and 19-inch racks including temperature + humidity probe
The Comet H3531R is a high-quality rack-mount thermo-hygrometer with Ethernet interface and two relay outputs. The device was specifically developed for online monitoring of temperature and relative humidity in 19-inch cabinets and is ideally suited for server rooms, data centers, and technical installations.
The H3531R features three binary inputs for capturing two-state signals and two relay outputs for controlling external devices. In addition to temperature and humidity, the device calculates the humidex as well as other humidity values such as dew point, absolute humidity, specific humidity, mixing ratio, and specific enthalpy.
The device is supplied with a T+RH probe with 1 meter cable. Optionally, probes with 2 or 4 meters cable length are available. The measured values can be monitored online in the COMET Cloud, with the COMET Database Software, or integrated into third-party systems.
