The OXY-SEN™ Oxygen Monitor is an economically priced percent oxygen monitoring system equipped with a standard measuring range of 0-100%. Available as an option, are dual 4-20 mADC recorder outputs that are scaled over 0-100% and 0-25%.
Our CE approved O2 monitor features an extended life, ambient temperature electrochemical sensor that is extremely resistant to a variety of acid gases, including carbon dioxide. The front panel has an easy to read, 3-1/2 digit liquid crystal display. Input power to the OXY-SEN is 115/230 VAC, 50-60 Hz or 24 VDC . The OXY-SEN can be wall/panel mounted or used as a bench-top device.
O2 Monitor Designed for Percent Oxygen Measurement Applications
Our O2 monitor was designed primarily for applications where the user prefers to mount the gas diffusion end of the sensor through a chamber, glove box, reactor, etc. The diffusion end of the sensor has a threaded stock, providing an easy and convenient way of installing the sensor through the wall of a chamber, glove box, etc. by simply drilling and tapping an appropriately sized hole. Ten feet of coiled interconnecting sensor cable is supplied with each OXY-SEN Oxygen Monitor. For gas tight integrity, the extended-life sensor is equipped with an “O” ring that helps to form a gas-tight seal. One advantage of using a threaded sensor is that it eliminates the need to use sample pumps or air driven aspirators to provide sample to the sensor. An optional, flow through sensor housing is available for applications where external sampling is required.

Oxygen Monitors Used To Ensure The Suitability Of Glove Box Atmospheres Oxygen monitors and analyzers are often used as a diagnostic tool to ensure the quality of the inert atmosphere within a glove box. Unlike a storage compartment within a car’s dashboard, however, there is another type of glove box used by industry, government institutions, and university laboratories. This “other” type of glove box (A.K.A. dry box) is a sealed enclosure designed to isolate reactive and/or hazardous materials. Glove boxes are typically fabricated from plexiglas, stainless steel, acrylic plastics, or a combination of the above and have (a) transparent side(s). The enclosures are equipped with gloves fabricated from rubber, Hypalon, or other chemical resistant materials that provide users the ability to manipulate materials within the glove box without risking contamination of the materials and concomitantly protect the user. Glove boxes can be configured as free standing devices or for bench-top use. When an inert atmosphere is required, the enclosures are normally purged with high purity nitrogen or argon. This inert atmosphere is maintained at a slightly positive pressure to help prevent leakage of air (oxygen contamination) into the glove box. Breathing air contains 209,000 PPM of oxygen. If the [...]
Measuring PPM Oxygen for Welding Applications Not all welding applications require inert shielding gas. However when it does, use of an accurate and reliable trace oxygen analyzer is an essential tool. TIG (Tungsten Inert Gas) welding of titanium requires the use of inert shielding gas, typically either high purity argon or a mix of argon/helium containing under 100 parts per million (PPM) of oxygen. Air contains 209,000 PPM of oxygen, so in order to create an acceptable atmosphere within the weld box (avoiding leakage of air into the box), a constant purge of inert shielding gas is normally applied. To help ensure oxygen levels within the weld box are at acceptable levels, a trace oxygen analyzer becomes a critical tool. Excessive levels of oxygen often lead to poor quality welds. The following video helps to describe the necessity of measuring trace oxygen in inert shielding gas. Caution should be exercised when selecting an oxygen analyzer for welding applications. When PPM oxygen measurements are required, avoid analyzers that only measure percent oxygen levels. Most of these types of analyzers use electrochemical sensors designed specifically for percent oxygen measurements, not parts per million. In such cases, welders often interpret [...]
