In Florida, traffic speed radar devices must be calibrated at least once a year. Additionally, they should be calibrated anytime they are repaired or after being involved in a significant event, such as a crash. Regular maintenance and calibration ensure the accuracy and reliability of the radar readings used in enforcement.
A digital thermometer uses electronic sensors to measure temperature and displays the reading digitally, while a mercury thermometer uses a column of mercury to measure temperature and has a calibrated scale to indicate the temperature. Digital thermometers are often faster and more accurate than mercury thermometers, and are also safer since they do not contain mercury.

Pipettes should be calibrated at least once a year or every 6 months, depending on usage and manufacturer recommendations. Additionally, they should be recalibrated whenever they are repaired, after a critical event, or if there are any concerns about their accuracy.
Mercury is most often found in thermometers.
Probe thermometers should be calibrated regularly to ensure accuracy, typically every 6 to 12 months, or more frequently if they are used in critical applications or exposed to extreme conditions. Additionally, they should be calibrated after any significant impact or if there are signs of malfunction. Performing a calibration check before each use is also advisable for ensuring precise measurements in critical situations.
An instrument for measuring temperature, often a sealed glass tube that contains a column of liquid, as mercury, that expands and contracts, or rises and falls, with temperature changes, the temperature being read where the top of the column coincides with a calibrated scale marked on the tube or its frame.

In Washington State, breathalyzers used for DUI enforcement must be calibrated every 30 days. Additionally, they should be serviced and maintained according to the manufacturer's specifications and any relevant state regulations. Regular checks ensure the accuracy and reliability of the breath testing equipment in legal proceedings.
Jet engines are not calibrated as such but get routine maintainance depending on the flying hours of the engine. They also undergo major overhaul and preformance runs during their life. But i think calibrate is the wrong term.
