For those of you looking for a manual extensometer, we now offer them. These are reliable and highly accurate machines that can start flashing a strobe when displacement has exceeded a predetermined distance. The design eliminates false alarms and allows the cable to be lengthened easily without having to go to the pin. It is also made of lightweight aluminum, making moving around even easier.
