ReLog L


The ideal vibration data logger for capturing and monitoring vibrations, shocks, and impacts. With superior battery life and 128 GB of memory, the ReLog is the perfect tool for monitoring vibrations in most environments. It has been designed to be extremely easy to handle and by the touch of a button, you will be up and running and measuring with up to 32,000 Hz sampling rate.

With its waterproof housing (IP67) there really are very few limitations to where you can use the ReLog! And when you’re done measuring the included software will make sure you have perfectly structured files that are easy to analyze and work with.
