The LT-120 TTT System

A Revolution in Tapping Torque Testing

Microtap USA’s latest model, the LT-120, addresses issues of flexibility, power and accuracy found with competitor or legacy machines. The LT-120 has both a wider range of available rpm and a higher maximum torque. The tests and procedures are economical, well documented and quick to carry out. The net result is that product modifications, manufacturing quality and competitive products can quickly be measured.

H. Roger Rowley

Roger started Microtap USA in 1996 operating alongside Photo-Tron Corporation, his electronics business formed in 1978. His training in electronic studies at Lawrence Institute of Technology and then as a controls designer, combined with product development at Photo-Tron, made Microtap a natural fit. Already familiar with working in Europe, Africa, and South America the world market of tribology gave Roger another avenue to satisfy his thirst for adventure travel. Pins on the world map in his office show seventy countries on six continents where he has visited or sold tapping torque equipment. On site installation and training from Microtap USA is not just a policy but his way of mixing business with pleasure. If there comes a market in Antarctica, please advise.
