Wzorcowanie„Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication” – VIM, 2008r.


Adiustacja“Set of operations carried out on a measuring system so that it provides prescribed indications corresponding to given values of a quantity to be measured” – VIM, 2008

It should be noted that calibration is frequently mistaken with adjustment which has a completely different purpose. The adjustment is performed in order to regulate a measuring device so that it yields the readings which are as close to the real values as possible. Having performed the adjustment it is necessary to re-calibrate the device.

Calibration of pressure measuring instruments in tenslab calibtration laboratory

CisnienieThe Calibration Laboratory is equipped with high-precision standard pressure gauges and pressure transducers which allows precise calibration of manometers, manovacuometers and pressure transducers within the range of -0.1 MPa to 70 MPa. The pressure is set using a pneumatic hydraulic pump. Due to the fact that professional measurement equipment is used, the Laboratory calibrates pressure gauges operating in a variety of working media: oil, water, air and alcohol. Pressure gauges are used, for example, to monitor pressure in various types of tanks and systems. The following groups of devices can be calibrated at our facility:
• digital pressure gauges,
• spring pressure gauges,
• pressure transducers.

Calibration of manual torque tools in tenslab calibration laboratory

Moment Siły

The Calibration Laboratory is equipped with high-precision equipment for calibrating manual torque tools in a wide range of torque. Torque wrenches and screwdrivers are used, among others in shipyards and automotive workshops. The calibration certificate issued by the laboratory contains the information regarding the actual torque setting.

Using a torque tool with an unknown actual torque setting may result in tearing off the head of the tightened or loosened bolt or deformation of the joined elements. . Manual torque tools can be calibrated in one or two directions. There are two groups of hand-held torque tools calibrated in our laboratory: torque wrenches, torque screwdrivers.
