Gemini’s Tinytag Energy Logger is a
non-invasive device for monitoring
power usage of single devices and
entire installations. Portable and selfconfiguring,
it can be used for spotchecks
or for longer term recording
to identify when equipment is being
used, times of peak load, how much
energy is being used and the overall
assessment of energy efficiency.

The device is suitable for
monitoring single or three phase
power supplies. Logging can be
initiated by the touch of a button, so
a laptop is not needed to
operate it on site. It
does not require
the exposure of any
live wires or
terminals so it is safe.

Non-invasive flexible
coils are used to
monitor the current in
each phase of a three
phase supply; voltage
information may be obtained via a
standard 13A wall socket. Stand J41
