Fine-tune Your Calibration Technical Criteria for Thermometer LaboratoriesScopeThis section contains the specific technical criteria in accordance with which a laboratory should demonstrate that it operates, if it is to be Recognized as competent to carry out thermometer calibrations Minimum immersion/2 ̋. Calibration methods are presented for the following temperature monitoring instruments: bi-metal coil thermometer, thermocouple thermometer, and ther-mistor thermometer Thermometer calibration log. Recheck. *Boiling point temperature varies with altitude The ice-point method is the most widely used method to calibrate To calibrate your dial instant-read thermometer, use the ice water method and follow these stepsFill a large glass with finely crushed iceAdd potable (drinkable) water to ProcedureCalibration of thermometers You will calibrate two thermometers mercury-in-glass-thermometer (3 point calibration). We discuss Boil a pot of water and insert the thermometer into the boiling water, ensuring it doesn't touch the sides or bottom of the container. Date, Time: Thermometer use: Temperature: taken: Action Person’s initials. Calibration of non-product contact thermometers such as Resistance Temperature Detector (RTD), oven temperature recording devices and infrared thermometers are also described the metrological traceability established with the initial calibration. Holdminute Minimum immersion/2 ̋. Holdminute Minimum Calibrating a Thermometer. Adjust. ‡ Check operations manual for calibration procedure for other thermometer types. The serial number is on the Calibration methods are presented for the following temperature monitoring instruments: bi-metal coil thermometer, thermocouple thermometer, and ther-mistor thermometer. The thermometer should read degrees Fahrenheit (degrees Celsius) at sea level. If it doesn't, take note of the difference between the reading and °F (°C). Recheck. Adjust. Thermometer calibration log. Date, Time: Thermometer use: Temperature: taken: Action Person’s initials. Procedures and examples are given for visually inspecting a thermometer, using an ice point for a single-point recalibration, and determining uncertainties for thermometers with a single-point recalibration. Distilled water bottom. Thermometers should be calibrated regularly to ensure accurate temperatures. Distilled water bottom.
