Capillary Thermostat Switch 50-300 Celsius Rotary Switch Temperature Controller - 2pcs

Expect a different part every time.

As another reviewer stated. The on-off differential is +30 degrees. I have tried 3 of these and same result with each.

very good products,it works like they said, I will recommend.

Cheap but they do work ok. knob calibration scale is a joke....... after it settles down I will paint new lines on the knob.

I used this on my electric smoker and am satisfied. After I got it centered, I let the smoker do it's thing. It does vary in temp by 26*F but my electric stove oven in the kitchen varies by 25*F which works for baking. Been using for a year and still works perfect. Set Dial @ 110*C = 230*F Temp fluctuates (26*F) from 226*F to 252*F (Perfect for Smoking)

These little things are great. I own a few industrial-process heaters that employ super-cheaply-made digital thermal controllers...that break after a year or so. Replacement cost on the cheap digital ones is fifty bucks or so, and that includes near-certain death in another 12 months. These inexpensive thermostats are reliable, and accurate enough for most applications. Maybe not for Aunt Sara's cryogenic freezer, but for my purposes they represent a big improvement on OEM for twenty cents on the dollar.

Used to Built a temp cutoff for my pellet grill so If I smoke a pork butt overnight I don’t have to worry about it turning into a fireball while I sleep. Wired both in series to my grill and either one will cut my grill off around 330 deg. The sensing lines are very small diameter so just got to handle them gently. Working good so far.,
