3 capacities, 50, 100, 200 grams / cN
The Checkline ZEF Digital Tension Meter is designed for simple and accurate tension measurement on yarns, fibers, and fine wires. A trigger-operated roller shifting mechanism makes it easy to acquire the running material, a large backlit color display offers 3 display modes and auto-rotation to allow for easy viewing in any measuring orientation.
The ZEF features 3 ball-bearing mounted small diameter rollers for measuring in hard-to-access locations. Optional rollers are available for high-speed applications. The ZEF automatically "zeroes" the display using a special position sensor.

- User-selectable units: cN, g, N and lb
- Storage of MIN, MAX, last reading, average, and standard deviation
- User-set MIN and MAX alarms with visual indicators
- Adjustable electronic damping for enhanced stability when tension fluctuates
- Automatic ZERO in all positions
- Storage for 3 Custom Material Calibrations
- CE approved
- NIST-Traceable Calibration optionally available
