Hot tech—new pyrometer for synthetic diamonds

To produce man-made diamonds for cutting tools and jewelry, gas molecules containing carbon are heated in a vacuum chamber for several weeks or even months. Maintaining a constant 950° C temperature throughout the process is essential.

Enter Keller’s new pyrometer, a device that has proven its ability to generate stable, accurate measurement signals at 500° and up, delivering the control required for high-quality synthetic gems.
