AVAILIBILE
The Model OX-600 is an indoor, stand alone 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-colour display, which changes colour 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 two different power options; 24 VDC or alkaline batteries. If on alarm, the user is notified by an audible alarm tone and the multicoloured LED digital display.
The OX-600 uses a 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. Additional alarms and strobes may be integrated into the monitor. It can also be wired into a BMS (building management system) if required.
