Digital Tension Meter for Sensitive Materials
3 Ranges up to 1000 g
For fragile materials sensitive to bending over a small radius such as optical fibers, carbon fibers, technical fibers etc.
The FTMB is a special tension meter for sensitive materials as optical fibers, carbon fibers, technical fibers etc. It uses low-inertia 32 mm dia. rollers for fragile materials sensitive to bending over a small radius. Rollers are available in plastic or aluminum.
