Tronic Single Phase Energy Meter

Our review

This is a fully electronic watt-hour meter built for single-phase AC supplies running at 50Hz or 60Hz. Instead of a spinning disc, it uses large-scale integrated circuitry with digital sampling and surface-mount construction to measure active energy, which is the kind of design that tends to hold its accuracy better over time than older electromechanical units. It suits homeowners, landlords metering a tenant's supply, or small workshops wanting a compact meter for a single-phase circuit. Before buying, confirm your supply is genuinely single-phase and that its frequency matches one of the two supported, then check the current rating your load needs, since that detail is not listed here. Compare against mechanical meters on accuracy stability and against smart meters on whether you actually need remote reading, because this unit focuses on straightforward energy measurement rather than connectivity. If you simply need dependable active-energy metering without extra features, this is the type to shortlist. It is available on Sokonia.
