AVAILABLE PROBE LENGTHS:
Probes are available in 1 to
4 meter lengths. If a longer probe lead length is required extension cables can be added to the probe to
accommodate the required length.

TEMPERATURE PROBE PLACEMENT:
Ideal temperature placement is a function of rack type, appliance
type, air flow and specific appliance location and density. As a general rule temperature probes are
placed on the intake (cool) or front side of the rack. This is to monitor the temperature of the input air
flow. The input air is monitored as it can be controlled where by the output or rear air flow is a function
of the device heat generation and input air temperature and flow. In high density applications, it is
recommended to monitor both the input (front) and output (rear) air flow. This allows for identification
of “hot spots” that may indicate devices are operating in excess of their thermal ratings.
