The MEC range offers a comprehensive assortment of robustly housed, cost-effective, digital toxic gas sensors, designed for original equipment manufacturer (OEM) systems. Our sensors are highly accurate, compact and versatile and have a long life expectancy, ideal for integrating into your breathing air system.
The Analox MEC Oxygen (O2) Sensor has been inspired by the proven 9212 range of electrochemical oxygen (O2) sensors.
The principle of electrochemical galvanic action is used by the cells to operate. This produces an electrical current proportional to the absorption of oxygen through a Teflon membrane.
The partial pressure of oxygen present is proportional to the absorption rate.
The sensor output is virtually immune to cross-interference, as neither the membrane or partial pressure of oxygen (O2) are affected by the majority of most other gases.
The 9212 series sensor within the Analox MEC Oxygen (O2) Sensor and the Analox MEC Oxygen (O2) Sensor itself are both field replaceable, which helps give them a long life expectancy and make them very cost-effective for the monitoring of oxygen.
Electrochemical cells are utilised by the Analox MEC CO sensors.
For monitoring carbon monoxide, the Analox MEC CO sensors are extremely cost-effective, with field replaceable cells that have a long life expectancy.
Integration into larger gas management systems has been made easy, with a digital serial communications interface.
Breathing in pure helium (He) can cause death by asphyxiation in just minutes. Inhaling helium (He) from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, blocking it. The blood vessels can rupture and haemorrhage.
The Analox ‘MEC He’ is ideal for integration into a breathing air compressor or system. Our sensors are highly accurate, compact and have a long life expectancy.
VOCs (volatile organic compounds) are any organic compounds having an initial boiling point less than or equal to 250°C, measured at a standard atmospheric pressure of 101.3kPa, and can cause damage to visual or audible senses. These include both man-made and naturally occurring chemical compounds.
Examples of common, everyday VOCs are gasoline fumes, paint solvents, air fresheners, construction chemicals such as carpet adhesives, dry cleaning and the gaseous portion of cigarette smoke. Along with particulates, VOCs are believed to be the major contributors to poor indoor (and outdoor) air quality. Most are thought to be carcinogenic in high concentrations and through long-term exposure.
Analox realizes that not all customers require a complete monitoring solution and prefer to integrate sensors into their own system, our range of sensors have been designed for this.
The MEC sensor range is ideal for this requirement if digital inputs are required. It is small enough to be integrated almost anywhere. Each housing has a gas port and using a simple flow adapter they can easily be installed in series in the gas path. An integral pressure sensor provides compensation for the effects
of atmospheric pressure where appropriate. The Analox MEC allows for easy replacement of sensor cells.
We also use MEC digital sensors in our own products, including the ACG+.
Note: If you wish to monitor sub-ppm levels of gas, the TEC range is also available.
