AMETEK MOCON  

As one of the most widely used gas detection techniques, the Photoionization Detector (PID), is commonly applied in both portable and fixed instruments for detection of a wide variety of organic compounds and some inorganic gases in ambient air.

MOCON’s patented, award-winning piD-TECH® eVx™ plug-in photoionization sensor provides complete photoionization detection capabilities and is designed to be mechanically similar to major brands of electrochemical sensors. Outstanding features make the piD-TECH line of sensors the right choice for OEM manufacturers looking to include VOC detection capabilities in their handheld, mobile, or fixed devices.

Offering better value and design flexibility for OEM markets and incorporating state of the art technology that cannot be matched in the marketplace, the piD-TECH eVx detection capabilities and minimum detection quantity (MDQ) come in five ranges depending upon application requirements.

Our dedicated sensor engineers will assist you in integrating our intrinsically safe photoionization sensor into your products, reducing the time and cost associated with product development.

Manufactured to the highest quality standards, Alphasense develops sensitive, accurate gas safety sensors for a variety of applications, ranging from fixed and portable detection devices to environmental monitoring systems and networks. 

Our high-quality gas safety sensors can be relied upon to detect gas and vapour leaks before the physical signs of a leak such as dizziness, fatigue and loss of muscle control take hold. 

Alphasense gas safety sensors help to ensure the health of workers as well as the safe operation of equipment by actively monitoring the concentration of flammable, toxic or asphyxiant gas within an area. 

Our consistent pursuit of innovative, new technologies coupled with our 25+ years of experience as an independent gas sensor supplier allows us to manufacture reliable, superior quality gas safety sensors that our customers can depend on. 

Oxygen makes up 21% of the atmosphere by volume. This is halfway between 17% (below which breathing for unacclimatised people becomes difficult) and 25% (above which many organic compounds are highly flammable). The element and its compounds make up 49.2% by mass of the Earth’s crust, and about two-thirds of the human body.

Accurate measurement of Oxygen is core to Alphasense’s portfolio, whether it’s required for safety, medicine, air quality or specialist processes.

Alphasense Oxygen Sensors (O2 sensors) have proved the test of time as cost-effective, low cost and robust in a host of applications.  Unlike partial pressure oxygen sensors, our design has good pressure and temperature dependence, making it the best choice in safety applications.  Our lead-free O2 sensor range has a significantly increased lifetime over a lead-based sensor – minimising the likelihood of sensor leaks and making mid-contract servicing a thing of the past.

We supply sensitive, high-performing air quality sensors in several formats for the OEM industry, suitable for a range of different applications in fixed or portable detection instruments.

Alphasense air quality sensors accurately monitor the presence of dangerous air pollutants and toxic gases in real-time – indoors or outdoors.

Our range of responsive gas and particulate sensors is supported by over 25 years of design and manufacture experience. Each product is performance tested with our unique Automated Test and Validation System, ensuring complete stabilization to deliver repeatable, reliable results.

Particulates & aerosols are most dangerous components of poor quality air and we know that the size and composition of these particulates determines their toxicity. At Alphasense, we pioneered a range of  Optical Particle Counters (OPCs) designed by aerosol scientists and engineered by Alphasense, delivering high-quality particle counts and sizing at affordable prices. The range has continuously evolved since to offer the best quality, low cost devices on the market.

In response to long-term projects in highly polluted urban environments, Alphasense has further ruggedized the OPC-N range and improved functionality in line with the demands of commercial applications. The latest OPC-N3 has the same dimensions and power/interface as the older OPC-N2, however it now measures from 0.35μm to 40 μm and sorts into 24 size bins.

The OPC-R series gives excellent performance in a device which is not only extremely small at just 70mm long x 21mm diameter but is also extremely cost effective. The OPC-R2 superseded the OPC-R1, bringing with it improved small particle detection, reduced fan noise and better EMC protection than its predecessor. The R1 and R2 have identical power requirements, communication protocols and data formats meaning that upgrading or transitioning from R1 to the R2 is painless.
