UV/Vis calibration meter chosen by Ministry of Defence

The Levy-Hill MkVI radiometer/ photometer from Applied Scintillation Technologies Ltd has been chosen by the Ministry of Defence (MoD) for calibration of light sources used for flaw and crack detection. With a major order placed through non- destructive testing specialist. Advanced NDT Instruments Ltd, the MoD joins an ever-growing customer list for these meters, which includes GE Aircraft Engines and GKN Westland.
The instrument is a hand-held, dual- action portable unit for quantitative measurement of UV or visible light intensity. It is used for UV lamp calibration and ambient light level measuring as part of fluorescent penetration and magnetic particle inspection methods. These are used for the detection of surface and near surface flaws on critical components in aerospace and automotive castings and structural engineering.
Calibration in these techniques is essential to ensure that the UV lamp emits the correct amount of UV light with the minimum of visible light interference ensuring flaws are not missed. In addition the meter can be used to check that ambient lighting conditions are acceptable.
The lightweight and robust meter is characterized by a large area integrated detector head, designed to minimize errors from hot spots within the lamp under test. An automatic back-lit display allows measurements to be made in low light levels or under UV operation. The unit complies fully with British Standards BS EN ISO 3059:2001 (for UV operation), BS667 (for white light operation) and comes fully calibrated under the quality assurance requirements of BS5781/ ISO 10012/1 (1992).
Applied Scintillation Technologies is a designated calibration authority for leading aerospace and defence companies, offering a full calibration service traceable to national standards. The company also offers a UV and white light repair and calibration service.
