Tradelab carries out the calibration of tension meters with 3 contact points with ENAC (ILAC) accreditation.
The calibration consists in generating a known tension in the cable, either by means of standard weights or by standard forces generated in a calibration bench.
Due to the influence on this type of instruments of rigidity, texture, surface irregularity and other physical characteristics of the cable, strip or wire, the calibration is done only for specific samples of cable, strip or wire.
The calibration is made in 6 points on the scale, from 10% to 100% of the full scale.
