The COVID-19 pandemic took us all by surprise this year. It has affected everyone and every business. A very large portion of manufacturing was shut down in an effort to “flatten the curve,” and even those who remained open have dealt with COVID issues such as employees who are afraid to come to work for fear of being exposed.

Proper Use of IR Temperature Sensors (Part II)

Accurate temperature measurements are critical to forging processes and the metallurgical properties of forged components. For a given set of specific conditions, IR temperature sensors work reliably and produce repeatable temperature measurements – but not necessarily accurate ones. Accuracy comes from properly calibrating sensors to the specific materials and applications.
