3 Tension ranges from 2 - 200 cN to 50 - 1000 cN

Special tension meter for sensitive materials as optical fibres, carbon fibres, technical fibres etc.

Hand-held unit with large guide rollers (32 mm groove diameter) to minimize material deflection

Tension meter with special guides on the bracket assembly for easy thread

Special Features

• 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

Standard Features

• Everything in operator’s view:
  - the guide rollers
  - the measured material
  - the readings
• Filament guide and roller shifting mechanism ensure easy acquisition of the running material
• V-grooved guide rollers, ball-bearing mounted
• Tension meter with rugged aluminium housing
• Certificate of Compliance with the order 2.1 according EN 10204 is included
• Optionally availlable: Inspection Certificate 3.1 according EN 10204 with calibration report
