    72-1006-10 OX-600 Indoor Stand Alone Oxygen Monitor, 0-25%, 115 VAC Operation with 10 Meter Sensor Cable by RKI Instruments

    RKI's Model OX-600 is an indoor, standalone monitor that detects Oxygen (O2) with a range of 0-25.0 % volume with 0.1% increments. It's sleek, low-profile design is equipped with a unique 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 and 10 foot power cord. 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 low-cost plug-in style galvanic cell sensor. This long life sensor is fieldreplaceable with no special tools required. The sensor can also be remotely mounted with an optional remote sensor cable.
