The MultiRAE Lite is an optimal one-to-six-gas monitoring solution for personal protection (including confined space entry) and multi-gas leak detection applications. Available in pumped and diffusion versions, featuring the broadest selection of sensor options in its class, and natively supporting 18 languages, the MultiRAE Lite can be configured to exactly meet the needs and compliance requirements of various countries, industries, and applications.

The MultiRAE Lite’s wireless capability elevates worker protection to the next level by providing safety officers real-time access to instrument readings and alarm status from any location for better visibility and faster incident response.
