“…While recently performing a uniformity survey on two L&L furnaces for an aerospace client. I was amazed by how uniform both these furnaces were. Both furnace uniformities were actually +2°F at lower temperatures and +5°F at higher temperatures…In the fifteen years I have conducted temperature uniformity surveys, which include many types of furnaces, this is one of the BEST I have ever tested…I will not hesitate to recommend to any one of my clients who may be looking for an excellent, heat treat furnace. L&L Special Furnace has my vote of confidence.”
