Designed for NDT lamp, multi-parameter simultaneous measurement

UV power and visible light illuminance, two important parameters of NDT lamp, can be measured at the same time to ensure that the lamp can play an effective role in magnetic particle testing and penetration testing.

 

Professional UV detector with high-precision UV filter

The UV measurement uses high-precision UV filter and professional UV detector. It almost no response to visible wavelengths, eliminate the impact of other spectral bands on the measurement accuracy. More accurate than ordinary illuminance meter.

 

Advanced digital probe technology

The instrument uses advanced digital probe technology, digital signal processing done directly at the probe.This reduces interference and provides excellent measurement accuracy.

 

Measurement of CCT

Correlated color temperature measurement helps to establish a standardized inspection process, assist in optimizing lighting conditions, improve defect visibility and increase inspection accurac.

Intelligent statistics function

Maximum values of UV power and visible light illuminance can be counted intelligently, which is useful for data analysis.
