The PPM gas sensor – MiniPID 2 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 PPM gas sensor 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 sensors@ionscience.com for further support).
