  • A resettable day counter as well as a total, which is what makes a meter useful for an experiment
  • A live load indicator, so the meter shows what is happening now rather than only what has happened
  • No accuracy class and no MID approval, at a price close to the two meters that have it

Best for: Working out what a circuit actually uses, day by day, before deciding anything.

A total that climbs, and a day counter you can zero.

Two readings

The running total, which is what a meter is. And a freely resettable day counter, which is what makes it useful.

A total answers “how much since installation”. A resettable counter answers “how much did that cost” — one wash, one day of sun, one night of heating. That question is the one people actually have.

The load indicator

Real-time consumption as well as the accumulated figure. The meter shows what is happening now, not only what has happened.

The display

Backlit, available in different colours, described for reading in poor light. In a meter cupboard that is not decoration.

The width

3.9 modules, published as a module count. Only this meter and the EASTRON in this family give one, and it is the figure that decides whether there is room.

The lines this listing leaves blank

Any accuracy class, and no mention of MID approval. Two meters in this family at a similar price carry it, and if the reading has to divide a bill, that is the whole comparison.

Availability

German, French and Italian Amazon stores quoted 42 € to 53 € when this page was compiled.

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

Spanish Amazon catalogue carries an entry for it, with nobody selling.

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.
