GridLink provides highly detailed monitoring of not only the electrical power use and charectaristics of consumption, but also alows obtaining insights on quality and stability of the local electrical power.
Frequent measurement updates - every 5 seconds - are enabled by the use of an inbuilt cellular data connection which requires no installation of local networking equipment.
Robust IP65 rated enclosure allows for outdor installation or use in harsh enviroments.
These aspects make GridLink especially suitable for monitoring facilty power inlet points or other critical junctions or equipment.
