Portable Power Monitor


Whenever needed, you can identify the level of electricity consumption immediately at your worksite.

This single unit solves all the problems you have with power checking at your worksite!

You can rely on it for your energy saving activity.

Many of the currently used power meters are not suitable for easily measuring power of a variety of machines and distribution boards. As a result, the electric power of a great number of machines in worksites is left unmeasured.
Our Portable Power Monitor ZN-CTX21 solves such problems. It is the industry's first "portable power monitor for energy-saving activities at the worksite."
It is "usable for anyone" "with ease" and indicates measurements "on site" immediately.
This new concept-based Portable Power Monitor ZN-CTX21 will make a great contribution to energy-saving activities at the worksite.
