LS125 UV Light Meter+UVA-X1 Probe

LS125 UV Light Meter+UVA-X1 Probe


I.LS125 and UVA-X1 Probe Introduction

     The LS125 UV light meter is a smart host that can support 9 different types of probes. Its main function is data display. The UVA-X1 probe is one of the 9 probes equipped with the LS125 host. The probe's spectral response range is 260nm-400nm, calibrated at 365nm. The UV light meter is suitable for detecting the intensity and energy of aging test and sunlight.

3. Adopting advanced digital probe technology, all data collection and processing are completed inside the probe. Data transmission through digital signals with stronger anti-interference ability can ensure more stable test data.

4. With high-speed acquisition characteristics of 2048 times / second, the test data is more accurate.

5.Three measurement units can be switched, namelyμW/cm², mW / cm², W / m². Data conversion between different units does not require manual calculation.
