DTFB - DTFX Digital Tension meter with large rollers
Digital Tension meter with large rollers to minimize bending of materials like fiber optics, carbon and technical fibers.The model DTFB is recommended where the #prod:125902#>cannot be used.
The DTFX is can be used in places where the #prod:125905# cannot be used.
Note: This model does not include a material thickness compensator
- Large, V-grooved guide rollers with 32 mm groove diameter, ball-bearing mounted
- Special guides on the bracket assembly permit easy material acquisition
- Filament guide and roller shifting mechanism ensure easy acquisition of the running material
- Rugged aluminium housing
- Specific Test Report with calibration report optionally available
- Large bending radius assures gentle handling of the material being measured
- Everything in operator's view:
- the guide rollers
- the measured material
- the readings - Ball-bearing mounted, V-grooved guide rollers
- Battery operated (AC adapter for continuous operation available)
