ZEF Digital Economical low tension measuring instrument

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.

Tension Ranges

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
ZEF-50	0.50 - 50.0 cN	43	PA: 0.12 mm Ø	0.1 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.

Applications

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.

Complete Kit

All models are supplied in a foam-fitted carrying case with worldwide AC-Charger with interchangeable multi-plug adapters.
