Setting the Standard in Photoionization Detection Technology ...

The piD-TECH® eVx family of photoionization detectors offers the latest in technology and upgrades without compromising the award winning features that make the piD-TECH line of sensors the best choice for OEM Manufacturers. Providing better value, design flexibility and lower detection limits. These improvements include greater stability over temperature and humidity changes, integral shielding, improved response time and minimum detection limits down to 0.5 ppb.

These detectors are designed intrinsically safe and with a 4P platform for ease of installation in both portable and fixed gas detection units. For use in a myriad of VOC (volatile organic compound) monitoring applications including environmental and safety applications in the industrial, commercial or residential markets.
