Our range of Photo Ionisation Detectors (PID) for Volatile Organic Compound (VOC) monitoring.  


If you are not sure what the correct solution for you is or what lamp voltage you require please try our VOC Gas Search which will help to identify the response with each lamp type and provide you with the Ionisation energy required for any gas; you may search by name, synonyms or CAS Number.  


We have also provided a searchable copy of EH40 which will enable you to find the most recent STEL and TWA values for a broad range of substances.
