As part of calibrating temp system, I analyzed several known good thermistors to generate reasonable Steinhart-Hart coefficients via curve matching of resistance measurements at various temps (e.g. 0'C, 20'C, 67'C, and 100'C). Results:

R_T=R₂₅exp{B{(1/(T+273.15)-1/(25+273.15)} OHM

where:

R25=400, B=4100
