I'm looking to get a couple of K thermocouples, and I also need to measure a few 0C-300C (or thereabouts: Oil temp, water temp, charge air temperature in turbocharged engine). Should I use thermocouples or thermisotrs for the lower-temp group? Any recommendations as to a good place to get a few for cheap? I'm planning on reading the thermocouples with ICs on an I2C bus round-robin fashion.
