3 Tension ranges from 2 - 200 cN to 50 - 1000 cN
Tension meter with special guides on the bracket assembly for easy thread
Tension meter DTFB
Special Features
top
- Large, V-grooved guide rollers with 32 mm groove diameter, ball-bearing mounted
- Large bending radius assures gentle handling of the material being measured
- Special guides on the bracket assembly permit easy material acquisition
- Tension meter model DTFX is calibrated using only PA monofilament!
- The design is otherwise according to model DTMB respectively model DTMX, but no material thickness compensator
For additional Information, see model DTMB and DTMX
