Environmental Monitoring Sensors

Dewpoint, Temperature and Humidity Sensor


The Geist GTHD Data Centre Temperature, Humidity and Dewpoint environmental Sensor collects and transmits real-time dewpoint, temperature and humidity data to protect critical data centre equipment from heat and moisture and offers two RJ12 ports, one uplink port to connect to a host device and a supplementary input for daisy-chaining.

The GTHD Temperature and Humidity Sensor requires a host device to transmit information. It counts as a single digital sensor while reporting multiple temperature readings.
The Data Centre Temperature, Humidity and Dewpoint Sensor can be positioned anywhere in your data centre and may be daisy chained with other GTHD or GT3HD sensors to form a sophisticated climate monitoring network with real-time data logging and alarming. This is especially useful when achieving in-row temperature monitoring for top, middle, and bottom of each rack as per ASHRAE guidelines.

The plastic enclosure mounts easily anywhere in the server room with screws, magnets or adhesive.
Specifically ideal for mounting on ceiling tiles within hot and cold isles in data centres.
Each GTHD comes standard with a 10ft’ (3m) uplink cord.
