H&L Instruments is the worldwide leader in development and marketing of electro-optical equipment. The company was established in 1979 and developed edge profile comparators for inspecting aircraft engine and power generating turbine blades, semiconductor wafers, and grinding wheels. We then developed the first-ever repeating fiberoptic modem, expanded our operations into fiberoptic communication, and created a solution that revolutionized how companies manage their distribution automation and SCADA systems. With thousands of modems, multiplexers, and transceivers installed worldwide, and its line of edge profile comparators, H&L Instruments has a range of products with a history of ruggedness, reliability, and trouble-free operation.
