Reliable, high accuracy safe area monitoring

For applications such as ambient air monitoring, inerting or gas cylinder storage, you need an adaptable, high performance O2 analytical solution you can truly rely on. Your job demands maximized efficiency, so your gas analysis needs to be highly stable and reliable. It has to be capable of easily integrating into your existing safety infrastructure and flexible in terms of settings and options. No matter what processes you are operating, the need for affordable cost of ownership is a must. We don’t believe you should have to compromise.

Non-depleting sensor performance

The Oxy 1800 utilizes Servomex’s world-leading Paramagnetic O2 sensing technology, which provides highly reliable, accurate and stable percentage measurements of O2. Unlike electrochemical technologies, the non-depleting technology requires minimal calibration and never needs replacing. The result is a long life with low maintenance costs.

Affordable, value-added features

The Oxy 1800 features have been specifically designed to ease everyday operation and maximize performance. Optional high flow cell, automatic flow control device (AFCD), back pressure regulator (BPR) and sample flow switch allow a fit to existing sample systems and aid overall performance, whilst also offering preventative maintenance.
