|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.
There is a button above the OK button that says Cable Size. Pushing that button will rotate the cable sizes until you get to your cable size you are looking for. So, yes you have you do have to key in the cable size. The cable sizes in this Tension Meterare 1/16, 3/32, 1/8,5/32/3/16. Measures from 10-150lbs.
In the US, the Gripper is certified every year, but in Canada, if you pass the 1st certification you get to certify your unit every 2 years. Calibration cost should range from $131.00- $175.00.
