Particle Counter Calibration Laboratory: ENAC accreditation

The Particle Counter Calibration Laboratory is accredited by ENAC with accreditation num. 80LC/10.055 in the 0.27 µm to 5 µm rangeto Particle size and in the 0,3 µm to 0,5 µm to Particle concentration. To carry out this type of calibration, the Laboratory has two calibration procedures, (TP001 &TP002), internal Laboratory documents covered by the ENAC accreditation, specifying all the steps to be followed to calibrate Particle Counters in Air or CPA. Carrying out this type of calibration begins with standard size particle suspensions certified by an accredited laboratory. It consists of determining the minimum voltage threshold of a counter to calibrate aerosol suspensions containing monodispersed particles of a known size. By this method, the ratio between the particles size and the signal detector output voltage of the equipment to be calibrated is determined. When this ratio is determined, the procedure to determine the particle size is applied starting with the voltage - particle size ratio.

The calibration process in Azbil Telstar Technologies, S.L.U.'s Laboratory satisfies the most comprehensive working procedures, which guarantee that a client’s equipment is treated with great care.

  • Equipment reception: the equipment to be calibrated is received in Azbil Telstar Technologies, S.L.U's Logistic Center. 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 Azbil Telstar Technologies, S.L.U's Calibration Laboratory under controlled environmental conditions. Duly identified and controlled reference standards are used during calibration. Azbil Telstar Technologies, S.L.U's calibration procedures are internal calibration documents that specify the steps to follow to perform 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: Azbil Telstar Technologies, S.L.U's Logistic Center dispatches the calibrated equipment. Special care is taken when packaging since this equipment is extremely susceptible to damage.
