About Safety Ratings for Electrical Testing

Voltage and Current Loggers

Record data over time to monitor energy consumption and troubleshoot intermittent problems such as voltage spikes. These loggers connect to a computer to download data for later analysis.

Set the sampling interval to determine how often the logger takes measurements. True RMS loggers take more accurate AC measurements than other loggers.
