There are at least three main reasons for calibrating measurement instruments:
The regular monitoring and calibration of measurement instruments is a mandatory requirement under the ISO9000 standards.
The Size-Length laboratory is located in a standardised grade 1 measuring room (according to the VDI / VDE 2627 standards), conditioned as follows:
We specialise in the calibration of the most common mechanical instruments, and are equipped to measure special tools:
Callipers / micrometers / gauge blocks / plain gauges / threaded gauges / cylindrical gauges / plain ring gauges for zero-setting / threaded ring gauges / indicators / height gauges / surface plates / machine tools / lines / laser distance measurers / square rulers / protractors / spirit levels / templates / custom parts / etc.
We calibrate and repair most electronic products.
The tools we calibrate include:
Multimeters / current clamps / oscilloscopes / generators / ohmmeters / LCR meters / data acquisitions / decade resistance boxes / earth resistance testers / hipot meters / network analysers / power meters / magnetic flow meters / etc.
Torque wrenches are used when clamping is important, in order not to damage the thread or to ensure load homogeneity in a mechanical part held in place by several screws or bolts. One example is given by the head of spark-ignition engines. It is extremely important to calibrate and fine tune these tools, to avoid defects or damages during assembly.
The calibration of torque tools is performed in accordance with the DIN/ISO 6789 and UNI EN 26789 standards, and is envisaged for the following tools:
|Torque wrenches||0.1 cNm - 3000 Nm|
|Torque screwdrivers||0.1 cNm - 50 Nm|
|Pneumatic screwdrivers||1 Nm - 100 Nm|
|Torque wrench calibrators / Static Torque Transducers||0.05 cNm - 3000 Nm|
The laboratory is equipped with thermostatic baths, hot ovens, a climate chamber, and a humidity and blackbody calibrator, to allow for calibration of the following instruments in accordance with international standards:
|Room thermometers||(5 ... 160°C)|
|Resistance thermometers||(-10 ... +450°C)|
|Hygrometers||(5 ... 95% Rh)|
|Infrared thermometers||(RT ... +450°C)|
|Thermographic cameras||(RT ... +350°C)|
|Contact probes||(RT ... +400°C)|
|PT100 probes||(-20 ... +160°C)|
|Thermocouples (K, J, ...)||(-20 ... +450°C)|
Calibration takes place using either a nitrogen calibrator or a hydraulic (oil) system, to allow calibration in the same conditions of use as the pressure gauge. To generate pressure, a reference master gauge is used, with accuracy up to 0.005%.
|Relative pressure gauges||-1 ... 700 bar|
|Absolute pressure gauges||0 ... 700 bar|
|Pressure generators||-1 ... 700 bar|
We are equipped to perform calibrations and controls according to and in compliance with international standards, directly at the customer's premises. This is necessary when the production cycle does not allow for equipment to be moved or removed.
As the only calibration laboratory in Europe approved by DSS Dynamic Solution Systems, we are able to calibrate balancing analysis tools, such as microvib II, accelerometers and all related accessories.
