"We have been working with PTI for a number of years. The technical service PTI has provided to our test instruments has been timely, professional, and of high quality."

We have been working with PTI for a number of years. We have relied on PTI to upgrade our existing tribotesters, as they provide excellent value for high quality work. The technical service provided to these instruments has been timely and very professional. Perhaps one of PTIs most notorious strengths is their flexibility to work with us to find a service and/or products that meet our budget and technical needs.

We have been involved with PTI since 1994. In that time, we have contracted PTI to remanufacture and upgrade 6 Pin & Vee Block test machines to like new condition. We operate these machines side by side with new Pin & Vee Block machines built by Falex Corp. We have also conducted reproducibility and repeatability studies and have found no statistically significant differences between the two groups of machines.

We have also purchased digital torque and load monitoring systems for all 10 of our Pin & Vee Block machines. We preferred the PTI monitoring systems over the Falex systems. We have also purchased two P.C. based data acquisition systems from PTI. To date, we have had no major complaints with PTI or their work. PTI has been very responsive when we have had problems.

"We had a Pin and Vee Block machine rebuilt by PTI. After receiving the upgraded machine, we were pleased with the quality of the work as well as the new digital upgrades. We have not experienced the inherent problems with the earlier models with this machine and ease of operation, maintenance, and calibration has been very cost effective and time saving in our organization.

We have found that talking directly to the engineers and builders of the instrument rather than a sales person greatly reduce any confusion concerning technical questions we have from time to time. We are pleased with the technical support from PTI and their willingness to assist us with other instruments not directly related to PTI products. We recommend PTI, Inc. as a supplier high quality technologically advanced wear and friction instruments and we plan to use them in the future."
