The Riken model OX-07 personal oxygen indicator and alarm is a pocket-sized, lightweight instrument designed for uninterrupted monitoring of oxygen levels. Carried in a pocket, the OX-07 provides hands-free oxygen level and an alarm whenever oxygen level falls below a preset point.

An alarm for low battery condition warns the user when power is low. The top-mounted oxygen sensor is easily detached for mounting on an optional extension cable to provide remote sampling in tanks or manholes prior to entering these or other potentially hazardous areas.
