The 11.7 eV gas sensor is a simple plug-and-play sensor able to deliver a dynamic and dependable response to thousands of volatile organic compounds (VOCs) across many diverse applications.

The sensor is designed for both diffusive and in-line pumped sampling, delivering an exceptional response time and clear down. The MiniPID 2 incorporates lamps of exceptional brightness and stability enabling detection of less volatile and less readily sensed compounds reliably, over an extended period of time.

Note: Alumina polishing of MiniPID 2 lamps is appropriate for all MiniPID 2 lamps except the MiniPID 2 11.7 eV lamp. Instead, please use anhydrous ethanol or methanol (please refer to the MiniPID 2 manual for guidance or contact for further support).
