Circuit Meter

Description

The Circuit Meter from Jetlun is a highly accurate single-phase ZigBee-based AC energy metering solution that can meter up to 16 circuit breakers simultaneously. There are two models: (1) Support ZigBee communications (model RD77719); and (2) Support HomePlug communications (model RD71219).

The Circuit Meter can be used for measurement and verification (M&V), benchmarking, and sub-metering. The Circuit Meter is a low cost wireless metering solution that is ideal for retrofits and can be used towards Energy Star certification, LEED® certification, NABERS® certification and ISO 15000 certification.
