ZEF - ZED
Economical, Limited Access Digital Tension Meter |
4 capacities, 50, 100, 200 and 500 grams or cN
The new CHECK-LINE models ZEF and ZED Tension Meters employ a strain-gauge system for accurately measuring the running line tensions on a wide variety of yarns, fibers and fine wires. Its trigger-operated roller shifting mechanism makes it easy to acquire the running material.
Single-button automatic zero permits operation in any orientation while maintaining highest accuracy. |
 Easy-to-read LCD display with auto power off
| | Powered by rechargeable Lithium Ion batteries, 90 hr battery life with 3.5 hr charge | | Supplied in an attractive foam-fitted carrying case
| | Simple 2-key operation
| | ZEF V-grooved guide rollers are rated for speeds up to 900 m/min, or optionally, 2000 m/min |
| | ZED V-grooved guide rollers are rated for speeds up to 2000 m/min, or optionally, 3500 m/min | | NIST-Traceable Calibration optionally available | | Automatic ZERO in all positions | | User adjustable DAMPING to "average-out" tension fluctuations |

ZEF Models
Miniature rollers make these models ideal for delicate yarns/fibers and
fine wires as well as those application where access space is limited.
For Spandex and similar materials,
specify model ZEF-100-T. |
 |
ZED Models
This model is recommended for all other applications where miniaturized
rollers are not necessary. |
 |
|
| | | | All models are supplied in a foam-fitted carrying case with worldwide AC-Charger with interchangeable multi-plug adapters |
