  • Sale
  • Regular price £145.99

Manufactured in our UK workshop, this versatile meter simply plugs in-line with the 3 phase 415v supply (16A/32A options) and provides reliable digital metering with some useful advanced functions:

  • LCD display on the meter unit.
  • Unit connects via Wi-Fi to enable live/cumulative readings and reports over time to be viewed on any phone or tablet.
  • The appliance connected to it can be turned on and off via Wi-Fi, offering full remote control.

A Wi-Fi connection is required to enable the unit to be switched on/off, the timer to be programmed or the meter readings to be accessed remotely. However, once programmed, the timer function will continue to operate without Wi-Fi and the on-board screen shows the meter readings.
