Rack mount environment monitor

Rack mount server environment monitor Hx531R

Also known as: remote server environment monitoring, computer room monitor, data center thermometer, temperature humidity IP sensor, computer room temperature alert. - temperature
- humidity
- power presence
- flood
- smoke
- air flow
- room entry

Server monitoring system is designed for 19-inch rack mounting, the height is one rack unit - 1U. Model H4531R is prepared for connection of external Pt1000 temperature probe and models H3531R, H7534R are equipped with 1 meter temperature + humidity probe. Unit also contains three binary inputs for detection of two-state events - e.g. power presence, water, smoke, airflow, glass break detection, door contact. Rack unit provides 5Vdc and 12dc power supply for external all sensors and detectors. Large dual line LCD for simultaneous display of temperature, humidity is an advantage. Parameters are easy adjustable from transmitter keyboard or from the computer. State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Environmental monitor is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured value.

APPLICATIONS - online monitoring of temperature, humidity, power, flood, smoke, airflow, room entry at:

- server and computer rooms
- data centers
- rack monitoring
- industrial Ethernet
- building management and automation
- telecommunication devices
