UV light measurement

Process measurements and validation

It is essential that any organisation operating UV light equipment as part of a critical process should monitor the UV levels to ensure the values emitted meet the minimum requirements for your particular process.

UV meters should have a similar spectral response to the equipment being used and be calibrated to suitable standards.

UV health and safety measurements

Standard UV light meters cannot be used to calculate or measure personal exposure levels but can be used to determine whether or not UV light is present. This can help identify any issues that could cause a safety issue, including, but not limited to:

  • Broken filters that could let harmful wavelengths through
  • Scratched or damaged coatings applied to tubes to block shorter, more aggressive wavelengths
  • Any light leak from UV machinery or systems designed to contain
  • Procurement of the wrong UV light source (spare bulbs or tubes)

UV light source evaluation

Determination of maximum permissible UV light personal exposure times for unprotected skin and eyes at specified distances from the source with recommendations for control measures. A typical UV light source measurement and assessment includes:

  • UV light spectral and irradiance measurements.
  • Classification in accordance with BS EN 62471 : 2008.
  • Determination of maximum permissible UV light personal exposure times for unprotected skin and eyes at specified distances from the source.
  • Control measure recommendations.
  • Comprehensive report.

UV transmission testing

Measurement of UV light spectral and irradiance transmission (%) through materials. Typical applications include:

  • Checking UV protection of clothing, spectacles, face shields, guarding materials and window films.
  • Determination of UV transmission through materials where required as part of your process.
