A biologist in our college wants to measure the temperature of ambient air
within a cave to monitor its effect on bats. I offered to do this for him
with Vernier temperature probes and a Texas Instrument CBL. We want to
calibrate the probes with a little more accuracy than we can get using the
freezing and boiling points of water. Does anyone know of any materials
whose melting and/or boiling points are in the vicinity of 15 C and whose
value is known well enough to provide calibration to within 0.2 C?
