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 line has been MOCON’s core PID sensor for many year. The eVx is a tested and trusted solution for OEM manufacturers looking to include VOC detection capabilities in their handheld, mobile, or fixed devices.
The eVx sensor is an affordable sensor that is easy to integrate and intrinsically safe. These sensors are proven solutions that are ideal for the industrial safety applications.
The piD-TECH eVx comes in four ranges depending upon application requirements:
- piD-Tech eVx -10.6 eV Green 0-10,000 ppm
- piD-Tech eVx -10.6 eV Purple 0-2,000 ppm
- piD-Tech eVx -10.6 eV Red 0-200 ppm
- piD-Tech eVx -10.6 eV Yellow 0-20 ppm
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.
