LS133 UV energy meter can display UV irradiation intensity, UV energy and temperature at the same time. This UV integrator is suitable for measuring various UV LED light sources such as 365nm, 385nm, 395nm, 405nm, etc. Mainly used in UV dryers, UV curing machines, mobile phone UV coating machines, exposure machines, printing presses and other equipment. UV radiation intensity and energy of UV light sources in the above equipment can be measured. The UV power puck is small as a bank card and the instrument body is slim, breaking the limitation of measurement space. It can be used normally in small spaces. For details, please watch the video below, LS133 UV integrator test the UV light intensity and energy of LED light source.

5. The real-time power value can be displayed during the measurement and the accumulated UV energy value and the maximum power value can be displayed directly after the measurement is completed.

6. This UV integrator use metal shell with high temperature resistant design, which can run in an environment of 100°C for a long time.

7. When the UV radiometer is off, long press the “POWER” button to enter the setting interface to set the measurement mode, trigger power value, smooth processing parameters and calibration standard. The parameter setting steps are shown in the following figure:
