The kits offered by us are from Germany. Our German partner is highly experienced in the field of retrofitting. They are the manufacturers of digital servo controllers used by many manufacturers of universal testing machines.Tension and compression testers have a very durable load frame. However, with aging of the machine, the electronics and application software become archaic and unpractical. In such cases, retrofitting your machine can prove to be highly economical as compared to buying a new machine without any reduction in the quality of the testing.
