Riken Keiki Logo


The Riken Keiki OX-07 portable oxygen monitor is a detector which can monitor the oxygen levels uninterrupted. The Riken Keiki OX-07 provides hands-free oxygen level and gives an alarm whenever the oxygen level falls below a preset point.

The Riken Keiki OX-07 Portable Oxygen Detector features a side-mounted jack that accepts a plug that connects to an optional alarm buzzer which can alert the wearer, even in environments with high background noises. A low battery alarm warns the wearer when the battery is low. The top-mounted oxygen sensor can easily be detached to be mounted on an optional extension cable for remote sampling in tanks or manholes.
