These PFA insulated thermocouple wire sensors are hermetically sealed at the sensor tip to provide continuous PFA protection over the measurement junction. This hermetic seal design provides a small, flexible, and electrically isolated thermocouple, suited to a variety of applications.
When using longer lengths, #20AWG stranded wire construction is available to reduce sensor resistance.
For a hermetically sealed RTD sensor, see the HSRTD

Tight ToleranceI bought this several weeks ago and the predicted 6 weeks for delivery.
I'm Happy with the accuracy and the price.

Best inert thermocouple I've usedHands down the best inert thermocouple I've used thus far. Our chemicals are very corrosive, so we were hard pressed to find a temperature probe that would work. Even coated, the sensitivity is great and consistency between the probes is great too. If I need more, I'm ordering this exact product again.
Will this thermocouple still work if exposed to sulfuric acid?

The Teflon is insulation is resistant to acids and oils.

Can any of these hermetically sealed tip thermocouples withstand temperatures below 0°C? If so what is the minimum temperature?
Asked by: JK018
Thank you for your inquiry JK018. The HSTC series is tested and guaranteed to measure temperatures accurately between 0 to 260 C. This thermocouple is made with Special Limits of Error (SLE) wire. Special Limits of Error Wire (SLE) made products are only spec’d out for temperatures above 32°F (0°C). So, anything below 32°F (0°C) does not comply with the SLE specification. You can accurately measured temperatures down to -80 C if you get a CAL-4 Calibration at an additional cost for temperatures below 0°C.

will this sensor (type K) work with the TX13 transmitter down to a temperature of -80 deg c
Asked by: Joe29
Thank you for the inquiry. Type K material is not tested below 0 C so the accuracy at -80 C would be suspect.
