Calibration of UV-meter at The National Laboratory
The National Laboratory for Photometry and Radiometry offers calibration of UV-meters.
Purpose
The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competens and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden.
A calibration performed at a national laboratory fullfils all typical traceability and accreditation requirements that commonly exist in industry and society at large.
Method
The calibration applies to UV-A and is performed against a Hg(Xe)-lamp with a band-pass filter at 365 nm with a bandwidth of 10 nm. The calibration can be performed at intensity levels from 50 µW/cm2 to 9000 µW/cm2. The standard service has a measurement uncertainty of 5% as a base but the measurement uncertainty can increase depending on the properties of the device under test. If a lower measurement uncertainty is required then that can be discussed as a speciality service.
We also have the capability to calibrate UV-meters for UV-B and UV-C as a speciality service.
The calibration takes place at the laboratory for photometry and radiometry in Borås.
Deliveries
The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.
