The RKI Instruments OX-600 is an indoor, standalone monitor that detects oxygen (O2) with a range of 0 to 25% volume with 0.1% increments. It is equipped with a tri-color display which changes color as oxygen levels reach each alarm level. The OX-600 has 2 preset alarms, and comes ready to operate with a simple wall mount bracket. It is capable of operating with three different power options; 115 VAC, 24 VDC or alkaline batteries. If oxygen is present, the user is notified by an audible alarm tone and the multicolored LED digital display.

The OX-600 uses a fast responding plug-in style galvanic cell sensor. This long life sensor is field-replaceable with no special tools required. The sensor can also be remotely mounted with an optional remote sensor cable.
