CL Meter is an energy metering device designed to measure, monitor, and report the energy consumption of an entire household or apartment building directly from the electric box or breaker panel, for users to look for energy-saving opportunities or provide tenant-specific billing. Installed directly in the home’s main circuit box, with the clamps attached to it, the CLMT-1ZW will monitor the total amount of electricity the entire home uses with accuracy and speed. With the CL Meter, users can easily track their power usage, allowing them to make the most out of reducing energy consumption and achieving greater energy efficiency.
