Key Features

Here are a few of the features of the eLogger:

Current is measured with a Hall Effects Sensor

Adjustable logging rate (from 50 samples per second to one sample every 5 minutes)

available sensors for about four hours, at 10Hz.

All data are logged to permanent memory, which retains the data even when the power is removed

Fully compatible with our OSD Pro expander

Includes Y cable for throttle position logging
