Flash Light Meter

UV-A Radiometer

Dual 365nm UV-A and White Light Meter

The Flash is the successor to the well-known Pollux radiometer for measuring UV intensity and white light levels when undertaking Magnetic Particle Inspection (MPI) and liquid Penetrant Testing (PT) methods of Non-Destructive Testing (NDT).

The flash is a 3-in-1 device which uses a single probe to measure UV-A light (Radiometer), white light (Luxmeter) and colour temperature (Thermocolorimeter).

The Flash Light Meter also features an internal memory for recording results and the ability for operators to access measurements and recordings remotely via USB and Wi-Fi interfaces as standard.

The Flash was developed according to ISO 3059 and ASTM E2297 / E3022 standards.

Designed with NDT in mind

The Flash Light Meter was designed to be the only light meter / radiometer an NDT operator would ever need.  The Flash utilizes data processing algorithms which makes verification of inspection lighting and ambient background light fast and ensures compliance with NDT standards is maintained, including ISO 3059 and ASTM E2297 / E3022.
