Current Only Data Logger

METSyS is a low-cost, simple-to-use 3-phase true RMS current data logger that is ideal for any load study application. Being a current-only logger, METSyS does not require a voltage connection, so it is perfect for applications such as connected load studies, compliance with NEC 220.87, breaker / circuit capacity evaluations, and more. The small flexible Rogowski coil current sensors allow for quick, safe, and easy connection to circuits to be measured.

Simplicity and Ease of Use

METSyS is simple to set up using its 2-line display or IOS / Android app. Its internal rechargeable battery allows for up to 100 hours (4 days) of logging on a single charge making it ideal for short-term studies. For applications where longer-term measurements are required, METSyS can be powered via the supplied USB power adapter.

Data Analysis and Communications

METSyS comes with a free iOS or Android app that communicates with the METSyS via Bluetooth that enables easy logger setup, viewing of live data, remote control of logger functions, and the option for emailing the logged data file.

Logged data can be accessed through the app or by using a USB Flash Drive. The data is stored in a comma-separated values (CSV) file format and can be simply loaded into a spreadsheet for graphing and review.
