The OX-600 is an indoor, standalone monitor that detects Oxygen with a range of 0-25.0 % volume with 0.1% increments. The OX-600 has two preset alarms and comes ready to operate with a simple wall mount bracket and a 10 ft power cord. An audible alarm tone and the multicolored LED digital display notify the user when O2 is present. The Monitor uses a fast responding low-cost plug-in style galvanic cell sensor. The sensor can be remotely mounted with an optional remote sensor cable.
