It is recommended you have your P.A.T.T.I. calibrated yearly if used regularly.
We offer competitive rates for calibration of a unit and single piston or discounted rates for a unit and multiple pistons. (chose your option below)
Our method is even suitable for ISO 9000!
- First, you must send your P.A.T.T.I. unit and pistons to our facility. Here your unit is fully checked out and the pistons are cleaned and lubricated.
- Then the unit is sent to NSTL (National Standards Testing Laboratory). There, NIST–traceable dead weights are applied to the piston depending on it's range. Air is then supplied to the piston from the control module in the same manner as a pull test. When the piston lifts each load, the value displayed on the control module is recorded. We then scale the values obtained based on the size of the piston and compare to the actual load on the piston over 4 points across the range of the piston.
- We perform this process twice for each piston. This allows us to effectively report the bias of each control module/piston combination.
This verification/certification procedure is performed at NSTL because they act as an unrelated third party and can certify our adhesion testers in an unbiased way.
