The Spectro-UV XRP-3000 AccuMAX is a compact, battery-powered digital radiometer/photometer designed for use in NDT applications such as magnetic powder (MPI) and penetrant (FPI). It measures both ultraviolet (UV-A) light and visible light using a dual spectrum sensor, making it particularly suitable for verifying inspection lamps in laboratory and field conditions.

Key features and benefits

• Measures both UV-A and visible light with a sensor that has two spectral wavelengths

• Automatic zeroing, “HOLD” to freeze the display, and “INTG” to show average intensity over time

• User selection for language display – support for multiple languages on the display

• Robust design with waterproof sensor housing and rubber protection for field use

• Compact and lightweight – designed for practical use in production, workshop and field inspection
