Has anyone ever used this model T-stat Ranco ETC-111000 Ill upload a picture in a sec. I have it on a incubator I made out of a large wine cooler about 2' wide and deep and about 6' tall. It seems to be holding the temp within .5 degrees. More details to come.
Temperature variation between on off times is regulated via the term ( hysteresis) most all thermos have it labeled on the PCB board. Really any thermostat will function in a incubator if it will regulate temp in a closed range of about 80 to 110 degrees Ferrite. This temp variance is regulated via a 1k - 5k potentiometer. ( also labeled on the temp adjuster) anything higher then a 5k will be very hard to keep the temp within 1 degrees. I have just finished a prototype of a 120v powered thermostat that regulates within 1/10 a degree and will switch a 12v or 120v heater if your looking for one. Myself and 3 electro engineers just completed it last week. I am using them in my incubators that i am selling. i am selling them for around 50 dollars. i will have one on display at the swap in ga on the 7th if you live close enough to come out. I am going to try to have a few with me to sell there but if i don't or i just run out of them then i will take orders for them.
