If power use rises or falls outside of user-set limits, the sensor alerts you via text, email, or call. Like all ALTA Wireless AC Current Meters, these 20 amp sensors can also issue energy status updates.

Turnkey Install

Install an ALTA Wireless AC Current Meter within 15 minutes: mount or affix the housing, then wrap the current transformer around the “hot” wire of a two-wire power system.

The ALTA 20 Amp Current Meter is offered in a discreet enterprise-grade model or weatherproof industrial housing, making either an excellent fit for business and machine monitoring. Save money and prevent downtime with one of the sensors below.
