Accredited particle counter calibration
Particle counters are used to monitor controlled environments and demonstrate compliance with airborne particle concentration requirements in accordance with ISO 14644-1 and ISO 14644-2.
Medico Support provides ISO/IEC 17025 accredited calibration of airborne particle counters in accordance with ISO 21501-4. We calibrate a wide range of particle counters, including Climet models, using traceable reference standards and validated methods.
Calibration is performed under DANAK accreditation, Accreditation No. CAL491.
Parameters described in ISO 21501-4
ISO 21501-4 specifies several important parameters for evaluating the metrological performance of a particle counter:
- Size setting error
- Counting efficiency
- Size resolution
- False count rate
- Maximum particle number concentration
- Sampling flow rate error
- Sampling time error
- Response rate
- Calibration interval
- Reporting of test and calibration results
Additional monitoring of instrument condition
In addition to the parameters described in ISO 21501-4, it may be relevant to monitor further technical parameters. These measurements can provide valuable information about the instrument’s current condition, stability and expected service life.
- Threshold voltage
- Laser diode voltage
- Stray light
Calibration in our laboratory or at your site
Calibration is normally performed in our own laboratories. Depending on the type of equipment and the scope of the assignment, on-site calibration at the customer’s premises may also be available.
All work is carried out by experienced and qualified personnel with up-to-date knowledge of applicable standards and requirements. We also provide professional guidance when selecting and purchasing new measurement equipment.
Total Service Agreement
For selected types of equipment, we can provide a comprehensive service agreement tailored to the equipment and the customer’s requirements.
Preventive maintenance and performance testing can help assess the condition of the equipment, reduce the risk of operational interruptions and extend its service life.
