Digital Tension Meter

Model ZEF

0.5-100.0 g

1-200 g

Model ZED

1-500 g

The New CHCKE ٠LINE^® models ZEF and ZED 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.

FEATURES

    Easy-to-read LCD display with auto power off

    Simple 2-key operation

    Powered by two (2) AAA alkaline batteries

    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

    Supplied in an attractive foam-fitted carrying case

    NIST Calibration available

ZEF Models

Miniature rollers make these models ideal for delicate yarns/fibers and fine wires as well as those applications where access space is limited.

ZED Model

This model is recommended for all other applications where miniaturized rollers are not necessary.
