Very nice polished finish.
I purchased this RTD to monitor the temperature of a keg washing system at a small craft brewery. It fit perfectly and works great!

Is this sensor UL certified? I haven't been able to find any documentation relating to that. Thank you
Thanks for your inquiry, RTD's are not UL rated. Therefore this probe is not UL certified.
