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.
