The GTHD/GT3HD Sensors provide real-time temperature, humidity and dew point data back to the host unit for data logging and alarming. These sensors can be daisy chained using the Remote Sensor port or another sensor can be added to this port. The GTHD and GT3HD sensors are the same with the T3HD having two additional RJ12 ports for adding remote temperature (RT) sensors. GTHD/GT3HD sensors are connected to host unit with provided RJ12 patch cable. Add up to 16 sensors per host unit for most platforms. The enclosure is designed for easy mounting nearly anywhere using screws or adhesive.
The GTHD is especially useful for watching out for rapid temperature drops and/or high humidity that can cause condensation to form on electronic equipment, resulting in hardware corrosion and component failure. Electrostatic discharge is likely to occur at low relative humidity levels, which can severely damage sensitive IT equipment. Based on ASHRAE’s recommended humidity range for IT equipment, we suggest setting relative humidity alarm thresholds for when the value exceeds 55% or falls below 40%, however each facility is unique and may require varied ranges.
