PFA Coated Probes are the perfect solution when there is a need to measure the temperature of caustic or corrosive chemical solutions in industrial and laboratory environments. The superior corrosion resistance of PFA allows you to measure the temperature of sulfuric, hydrochloric, nitric and chromic acids, as well as caustic compounds.

Examples of some popular models are listed in the To Order Box. For full configuration availability please use the Part Number Builder.

Rated 4 out of 5 by from Great probe for safety! Does a great job of keeping user's hands away from hazardous chemistries being measured. Nice to have a few choices of lengths. Nice quick connector.... no special connector to have to build.
