The professional-grade CT-327 wattmeter clamp is one of the most advanced instruments in its class. In addition to its capabilities of power and energy measurement (active, apparent and reactive), it can trace in its very own screen the voltage and current graphs as well as the harmonics with no need of using additional instruments.

Just insert a microSD card in the memory slot to store measurement records with an user-definable time between samples of 2 to 7200 seconds. The system accepts cards of up to 32 GB (an 8 GB card is included).

The CT-317 wattmeter clamp has a built-in real-time clock to attach the day and time to the measurements, transfer them to the computer and process them with any compatible application.
