|The Gripper, a wireless cable tension meter by Sprague Instruments. With more information on the display box screen and a much larger and more durable storage case than previous models.|
We had previously owned the original non wireless griper. It was a great tool except the wire would get caught on things. This new warless unit is much better. Easier to use. The reader is smaller and more user friendly. We have now rigged 3 aircraft with it without any problems. We at Bens Motorworks Highly recommend this Tensiometer
Yes the factory calibration certificates are included in the box.
