Features:
- 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.
- High-precision spectral sensor:The instrument is designed with a spectral sensor, and the spectral response matches the V(λ) function. This ensures accurate measurements.
- 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.
- 1,000,000 Lx and 200,000 μW/cm² large range:the UV power range of the instrument is up to 200,000 μW/cm², and the visible light range is up to 1,000,000 Lx. With the large range design, the demand for high intensity UV or extreme lighting conditions can be met, and fluorescent materials under strong UV irradiation and subtle defects under strong light can be tested.
