ZEF Digital Economical low tension measuring instrument
4 capacities, 50, 100, 200 and 500 grams or cNThe 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.

| Model | Ranges | Measuring Head Width* mm | SCHMIDT Calibration Material** | Resolution | |
| ZEF-100 | 0.5 - 100.0 cN | 43 | PA: 0.12 mm Ø | 0.1 cN | |
| ZEF-200 | 1.0 - 200.0 cN | 43 | PA: 0.12 mm Ø | 1 cN | |

| Other units of measure are available, such as g. * Width of filament guide ** Suitable for 95% of applications - PA = Polyamide Monofilament Special calibration using customer supplied samples is recommended, if process material differs significantly from the SCHMIDT calibration material in diameter, rigidity or shape. For this purpose a material sample of about 5 m should be supplied. | |||||
| ZEF Models
Miniature bearings make these models ideal for delicate fibres/yarns and fine electrical wires, as well as for applications where access is restricted. For Spandex or similar materials, specific model ZEF-100-T. |
