Our History
1946
The David L. Ellis Co. was formed by David L. Ellis, a high temperature metallurgy specialist. He represented various companies until his retirement in 1983.
1983
Richard A. Ellis, David's son, incorporated the company after leaving Wilson Hardness Testing Instruments where he was a district manager for Eastern New England. DLE began selling and servicing accredited hardness testers.
1986
The company manufactured its first Rockwell Hardness Test Block.
2000
DLE became NVLAP accredited — and remains so today. The company now ships Rockwell, Brinell, Vickers, Knoop and LD blocks all over the world.
Today
DLE is an accredited lab for hardness testing. If you have low volume and cannot justify the cost of high quality hardness testing equipment, call us and we can measure your parts for you.
