If a calibration point below the dew or frost point is made, a provision should be made to prevent ice or moisture build-up on the calibrator surface. Therefore, if you are measuring an instrument using an ice bath, you should read zero (0) (32F) exactly. Higher quality more expensive units will have accuracy spec'd to temp ranges and the colder ranges can x2 and x4 less accurate. There are two generally large uncertainties that arise when using Scheme I: the emissivity uncertainty and the source heat exchange uncertainty. Load the ice cubes to the ice shaverStep 4. Lets go a little down to discover it. Be the first to write a review. Could you give me a quotation for the training? Now, get the error from the result of the calibration above. The Fluke Calibration 4180 and 4181 provide a measurement point so that the calibrator surface does not have to be touched. Figure 9. For example, if a thermometer has distance-to-spot-ratio of 12:1, that means that at a distance of 12 inches, the measurement spot (field of view) will be about 1 inch in diameter. Accuracy increases as IR energy radiated increases. Crushed ice solution is reasonably straightforward to use. Here is a table showing the values that need to be considered when using aRayTemp 2 thermometerin cold or hot environments. Example of an uncertainty budget. In Scheme II, the true temperature of the source is determined by radiation thermometry. To choose an infrared thermometer, start with the industry standards. This could take any amount of time, depending on the response time of the inserted probe. Figure 1. Dip a thermometer into the ice bath to take a temperature reading.
