The OXM-100H is designed to verify oxygen purity from your oxygen generator real-time from 0-100%.  Simply mount this unit next to your oxygen generator and plumb your oxygen to flow through this unit to verify the oxygen purity. This unit has indicator lights for the oxygen purity level and has relay alarms when the oxygen purity is low.

An oxygen flow of only 0.5 SCFH is required to measure oxygen purity.  A needle valve and flowmeter are built-in to regulate and indicate oxygen flow through the oxygen purity meter.

The principle of operation uses ultrasound technology to measure oxygen purity.  The speed of the ultrasound varies with the oxygen purity and temperature.  This unit measures oxygen purity by ultrasound transit time and corrects this value for temperature.  This allows a reliable and consistent oxygen purity measurement with no sensor to replace.

The most important factor in your ozone systems reliability is the feed-gas quality provided to your ozone generator.  If the oxygen purity is kept above 85%, and this is a clean, dry stream your ozone generator will require less maintenance and offer many years of reliable operation.  The cost of an inline oxygen monitor is a very reasonable insurance in your complete system, and may pay for itself many times over.

Specifications:

- Measure oxygen purity from 0-100%

- Integrated display, large LCD display with alarm for low oxygen purity

- Relay alarm for low oxygen purity set to 88% 

- 4*--20 mA output standard

- Optional remote monitoring (wireless monitoring & data logging kit)

- Optional visual strobe light

- Optional audible alarm

Installation Diagrams:

The OXM-100H Oxygen Purity Meter is installed directly after the oxygen concentrator and requires a small flow of oxygen (0.5 SCFH) to flow through the unit to measure oxygen purity accurately real-time.

Installation:

The OXM-100H Oxygen Purity Meter is installed on a side-stream of oxygen flow.

Only 0.5 SCFH of oxygen is used to pass through the OXM-100H.  A needle valve is included with the OXM-100H to regulate oxygen flow through the unit.

Options:

Various optional equipment is available for the OXM-100H.  See details below for information.

Strobe Light:

An optional strobe light can be installed on the unit as a virtual indicator when oxygen purity is below 88% (custom set-points available).  The strobe will be integrated on the enclosure and be wired and ready for operation.

Audible Alarm:

An optional audible alarm can be installed on the unit to alert when oxygen purity is below 88% (custom set-points available). 

Wireless Monitoring & Data Logging Kit

Use the Wireless Monitoring & Data logging Kit with your fixed mount monitor to connect it to the internet allowing access from anywhere. Receive Instant notifications with free text and email alerts. This is a great addition for your fixed mount gas detector.
