PTFE Temperature Probes

PTFE encapsulated temperature probes combine the outstanding properties of PTFE with the accuracy and reliability of platinum resistance and thermocouple thermometry.

  • Inert to virtually all chemical reagents
  • Non-contaminating
  • Impervious to chemical diffusion at high pressure
  • Wide operating temperature range, -180 to +300C
  • Outstanding electrical insulation properties
  • Individually tested

We offer a standard range of probes or can custom manufacture to suit your exact needs - simply send details of your dimensions, type and quantity required for a quotation.
