UV light meters for measurement of personal UV light exposure levels to compare with exposure limit values
When assessing a personal UV light exposure scenario in the workplace, the crucial question is can a clear and unambiguous statement be made that the UV light exposure limit values are observed or exceeded.
Employers must assess the level of risk for adverse health effects by determining personal UV light exposure levels and comparing with the exposure limit values.
There are two UV light exposure limit values for broadband UV light sources and depending on the wavelength range of a particular UV light source, one or both may be applicable. It is necessary to comply with both, which is achieved by adopting the most restrictive exposure limit for the eye.
The following UV light measurements must be made at appropriate distances from the UV light source, dependent on any person's closest approach…
…measurement of UV-A light irradiance (EUV-A) in the spectral region 315 nm - 400 nm to assess compliance with the UV- A light radiant exposure limit value of 10,000 J/m2 for unprotected eye
and/or
…measurement of UV light effective irradiance (Eeff) in the spectral region 180 nm - 400 nm to assess compliance with the UV light effective radiant exposure limit value of 30 J/m2 eff for unprotected skin and eye
UV Light Radiometers
UV-A Light Irradiance Radiometer
- For measurement of UV-A light irradiance (EUV-A) in the spectral region 315 nm to 400 nm to assess compliance with the UV-A light radiant exposure limit value of 10,000 J/m2 for the unprotected eye.
UV Light Effective Irradiance Radiometer - Actinic

UV Meter Calibration
It is recommended that your UV light meter is calibrated every 6 - 12 months depending on usage. We offer a quick turn around for UV meter calibration.
