King Tester Corporation

King Tester Corporation makes hardness testers for metal. The company was founded in 1936 by Andrew King. He wanted to meet the need for a portable full load Brinell tester. Brinell is a method that presses a hard ball into metal to measure how hard it is. The company has made these testers for over 90 years.

The main products are portable Brinell testers and Rockwell testers. The company also makes patented test blocks and microscopes. The CaseRock Series checks case depth quickly. Case depth is how deep a hard layer goes into a metal part. All King portable Brinell testers are made in the USA.

Portable testers can go to large or hard to move parts. The company says they work in tight spots, and right side up, upside down or sideways. Rockwell testing can also be taken to parts that cannot come to a lab. The website also lists calibration, repair, maintenance and service for King equipment.

Quality standards are a key point. The company says its portable Brinell testers are built and checked to ASTM E10. Its laboratory is accredited to ISO/IEC 17025 for Brinell calibration by the American Association for Laboratory Accreditation. Calibration is traceable to NIST, the United States standards body.

Aerospace is one of many sectors served. The company says advanced alloys in aerospace need hardness testing to meet quality and safety rules. Other sectors named on the website include shipping, rail, oil and gas, foundries, steel and aluminum mills, heat treaters, military, automotive, infrastructure, construction and utilities.

For oil and gas, testers help meet American Petroleum Institute standards. Railways use portable testing for track and rolling stock. Foundries use it to check large cast parts against customer specifications. Customers range from large multinational firms to small, privately owned metal processors.

The company states that its mission is to follow its founder's vision. That means serving customers with high product quality and reliability, and good service. The website helps visitors choose a tester by application. It also gives a way to contact a technical representative.
