防水RTD PT100 温度センサー - Jaybva サーミスタプローブ PID温度コントローラー用 3ワイヤー ステンレススチール NPT3/4インチ BSPT 1/2インチ パイプスレッド 絶縁リードシールドワイヤー付き -50~500℃

Well made product did the job as expected for my outside fish pond.

I can't complain when a sensor just works and this it does. I have my K type probe connected to an InkBird PID controller, replacing the stock one it came with. This thermocouple screwed right inside the existing 1/4" screw terminal in my pot and sealed up nicely when tightened. The temps read pretty darn accurately and the stainless finish on the thermocouple appears to be up to par. The braided cord on this probe is quite long and prone to nasty kinks, so be careful with it. All things considered I will absolutely buy this again if needed!

I have long suspected that something is amiss in this lab and this PT100 probe has enabled me to prove it! 116.79, minus 0.56 for the resistance of two leads, minus 100 for 0℃.... divided by 0.385 equals.. Forty two! I knew it! This coffee is cold! Seems to work okay out of the box, I've seen some other reviews doubting its longevity but only time will tell that. I particularly like the three lead arrangement, it's quite a clever way to null out the resistance of two - leads by giving you a third lead to use as a secondary current path just for measuring two of the leads. Assuming that all of the leads are pretty much identical, this gives you a pretty good idea of how much you need to subtract from the reading across +/- leads with the sensor in between.

Not accurate at all. Fluctuates temperature all over the map. Do not recommend.

Es tal cual lo ofrecen. Muy buen producto.
