A pyrometer is a device used for measuring relatively high temperatures, such as those encountered in furnaces. They were originally designed to measure high temperatures, but some are now used to measure any temperature range.
- The English potter Josiah Wedgwood invented the pyrometer in the 1780s as he knew that porcelain contracts under high temperatures.
- Here is a photograph of his pyrometer:
