Description of the oxygen meter
The OX-600 is a stand-alone indoor oxygen monitor. It can detect oxygen (O2) in a range of 0-25.0% volume in 0.1% increments. The sleek, low-profile design is equipped with a unique three-color display that changes color when oxygen levels reach the respective alert level. It can be operated with three different energy options; 115 VAC, 24 VDC or alkaline batteries. When oxygen is present, the user is notified by an audible alarm sound and the multi-color LED digital display.
The OX-600 uses a fast-reacting, low-cost plug-in electrochemical cell (electrochemical cell) cell sensor. This durable sensor can be replaced in the field without the need for special tools. The sensor can also be mounted remotely with an optional remote sensor cable.
Extension cords are available up to 20m (gradation: 3, 5, 10 or 20m).
