However, even in the best baths, temperature gradients may still exist, and therefore it is important that both the reference and test thermometers be immersed to the same horizontal position during calibration to reduce errors. There are two easy ways to calibrate your thermometer: the ice water method or the boiling point method. Black bodies approximate zero reflected ambient radiation and therefore the unimpeded emission of infrared energy for a given emissivity value (typically 0.95). Confirm Accuracy Using a Blackbody. Which is More Accurate – Digital or Mercury Thermometer? Fill a large glass with ice and then fill it with cold tap water. There are mainly three ways we can calibrate a thermocouple. A blackbody is a theoretical “perfect emitter,” meaning it emits the maximum amount of infrared energy for any given temperature. Not sold in stores . Most electronic thermometers have a digital display that shows you the temperature reading. To calibrate a thermometer is to configure it to provide temperature readings within the standard range.
