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.

Tight Tolerance
I 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 used
Hands 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.

EXPECTATIONS EXCEEDED!!
I have ordered items from Omega several times over the last few months. These guys are AWESOME when it comes to customer service. Wether its been about
determining selection of a specific component in reference to our application or technical support of programming of soak controllers. Omega has consistently exceeded our expectations.

Will this thermocouple still work if exposed to sulfuric acid?
The Teflon is insulation is resistant to acids and oils.

can this thermocouple be submerged in water?
Thank you for your inquiry Lili. Yes, this thermocouple can be submerged in water. Please note that it cannot be submerged near the end where the two wires come out of the insulation.

Can any of these hermetically sealed tip thermocouples withstand temperatures below 0°C? If so what is the minimum temperature?
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.

If i choose T thermocouples from this type, can i measure temperatures in the range between-38°C and 0 °C. Thanks
Like this sensor, 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. Does this mean that measuring below 0°C is not possible? No. It just means that the accuracy is no longer linear below 0°C.

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