Software downloads & release notes

Electron Plus software is built to work exclusively with our hardware; it is free to download and use with our products. As with most software, there will be continuous updates (as well as bugs/anomalies). Any and all feedback is welcome, and we will do our utmost to fix problems in a timely manner.

Our instruments use USB<>serial bridge IC’s from several manufacturers.  We suggested you download and install these drivers BEFORE plugging in your instrument.
