Calibration and metrology

- July 19, 2012

Measurements are meaningless without reliable measurement instruments. Calibration assures engineers that their equipment is properly compared to known good reference standards. Those reference standards are then compared with even better standards, a path that flows to a national or international reference standard. Metrology--the science of measurement--relies on proven techniques to keep the calibration chain intact.

Calibration: It's what's not in the water that counts

  • 05.05.2006

Ask any New Yorker why New York bagels are so famous and you'll likely hear, "It's in the water." Whatever is in the water may be good for bagels, but is bad for temperature calibration. The impurities that make New York bagels taste good, like all impurities, affect the triple point of water (TPW)—the temperature and pressure where water exists in solid, liquid, and vapor forms in equilibrium, all at the same time.

Many professions have certifications for people who work in that field. Take engineers, for example; degreed engineers can become registered professional engineers. Technicians in many fields can take certification exams. But those who work in calibration currently have no such exam. Thanks to a new program, that's about to change. Read More...
