Whilst thermometers are really measuring their own temperature, they are usually needed to measure the temperature of the surrounding air. To ensure that the temperature of the surrounding air is the same as the thermometer, it must be shaded from sunlight and be exposed to adequate ventilation.
Dan DeBra) once said, roughly, âall instruments are first and foremost thermometers, but sometimes they measure something else as wellâ. He was talking about temperature compensating strain gauges, but he was also in charge of an ultra-precision machining laboratory â the one that built the gyros for Gravity Probe B.
