A MID meter for one circuit at a time.

What MID means here

The reading can be used where a number has to be defensible — a shared supply, a tenancy, a cost split. The title says certified and calibrated; what it does not say is which standard or which class, which the Orno in this family does state.

What it is for

The third bullet is unusually honest: this is a tool for breaking down the consumption of a single circuit. Not the house, not the incoming supply — one circuit, measured properly.

That is exactly the case in an installation with a heat pump, a charger or a solar array, where the incoming meter tells you nothing about which of them did what.

The display

A backlit LCD in a four-module case, showing real-time watts as well as the total. Readable day or night, which a meter cupboard needs.

The gap

No output. No pulses, no protocol, nothing to log. At a similar price the Orno meter in this family publishes 800 pulses per kWh, and that is the difference between a meter you read and a meter that reports.

Availability

German, French, Italian and Spanish Amazon stores quoted 50 € to 51 € when this page was compiled.

British Amazon store carries it too, priced in its own currency, which the euro range above deliberately omits.

American Amazon store returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

These figures are what Keepa reported on the day this page was last updated. Availability and pricing move without notice.
