Very disappointing!
Quality control and customer service needs improvement! I ordered 6 and only got 3 that worked. I sent the 3 bad ones back, and after months of waiting for the sensors that I needed months ago, I finally received 2 good ones and 1 bad one. I will not be using Omega again. Very disappointing!!!

Precise Temperature Control
Fairly accurate, but tip is delicate and you cannot bend it too much otherwise the internal thermistor breaks.

Need to improve quality control
This sensor is great when you get one that works. I ordered 6 and 3 didn't work. No prob I contacted Omega and they said send it back and we will send you new ones. After months of waiting they sent me 3 replacement sensors. Only two of those 3 sensors actually worked. I will not be using Omega for my futher needs.

Is this a NTC(negative temperature coefficient) thermistor?
Thank you for your email . The HSTH-44031-120 uses a NTC thermistor which
drops in resistance with increase temperature . The Thermistor Resistance vs. Temperature table is found per the attached link
