Helium Leak Calibration Laboratory

The Helium Leak Calibration Laboratory is accredited by ENAC with accreditation num. 80LC/148 in the 5x10^-7 mbar l/s to 5x10^-2 mbar l/s range. To carry out this type of calibration, the Laboratory has a calibration procedure, (TF001), an internal Laboratory document covered by the ENAC accreditation, specifying all the steps to follow for Helium Leak calibration. Helium Leak calibration is carried out by direct comparison with a carefully controlled and calibrated Helium Leaks. Our Reference Leaks are calibrated by a Reference Metrological Laboratory.
The calibration process in Telstar's Laboratory fulfills the most comprehensive working procedures, which guarantee that your equipment is treated with great care.

• Equipment reception: the equipment to be calibrated is received in's Central Warehouse. On arrival, the warehouse personnel assign it a unique ID to avoid any confusion. Warehouse personnel notify the Calibration Laboratory of the arrival of the equipment to be calibrated and take it to a special area.
• Calibration: laboratory personnel pick up the equipment and take it to the laboratory where it will be kept with a stable temperature and position for a minimum of 8 hours before calibration. Calibration is carried out in Telstar's Calibration Laboratory under controlled environmental conditions. Duly identified and controlled reference standards are used in the calibration. Telstar's calibration procedures are internal calibration documents that specify the steps to follow in performing calibration and the subsequent issuing of results. A calibration certificate is issued for each piece of calibrated equipment to the specifications required by ENAC.
• Dispatch: Telstar's Central Warehouse dispatches the calibrated equipment. Special care is taken when packaging, since this equipment is extremely susceptible to damage.
