The greenlight 300 has been developed to provide a reliable and accurate alternative to mercury devices. This is achieved using silicon chip technology replacing the traditional mercury column with an electronic pressure detection system. 

The greenlight 300 is non‑toxic, robust and importantly, automatically self-calibrates to zero when switched on, thus ensuring reliable accuracy.
