EDM Wire EDM Tension Meter

Made in Germany
Click images to enlarge.
The DX2-EDM Hand-Held Mechanical Tension Meters are designed to measure the tension on all current wire EDM machines with using a wire diameter of approx. 0.25 mm. These models are used throughout the world and considered the standard tension meter for the industry.

The correct erosion wire tension reduces wire oscillation and guarantees a pinpoint accuracy of your machines. Always check the tension in calibration mode on the moving wire. Make sure the generator is switched off for the tension check.

For meter calibrated in Grams add "-G" to part number, ie: DX2-2000-EDM-G

Material thickness compensator: For better accuracy the material to be measured or a similar material with the same diameter should be inserted (only model DX2-4000-EDM).
