I have an ic with a poorly performing thermistor I'd like to replace with a more accurate, more sensitive component. The first step is finding out what thermistor I likely have or at least who made it. If it wasn't garbage, it ought to perform with very high accuracy in the temperature range 80°F - 110°F (+- .5° or better) and with reasonable accuracy from 60°F - 125°F (+- 2° or better). I am aware that the accuracy is really a matter of the chip interpreting the resistance value from the thermistor... but something has to be wrong with this particular thermistor since I have two, and only this one is about 10 degrees off.
It is a bright blue, dipped component on two copper leads about 3.5 cm long. The product it's in is a chicken egg incubator currently made by Georgia, US poultry equipment company GQF. Unfortunately, they appear to have decided to do things on the cheap. (The cheep?) Although touted as a high tech, reliable option this particular electronic incubator takes wildly inaccurate temperature readings. I have another which reads temperature accurately enough to hatch chicks... Photos attached.
