For details, please watch the video below, LS133 UV integrator test the UV light intensity and energy of LED light source.

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.

Portable and compact

The thickness of LS133 UV integrator is 7.6mm and the width is 44mm, the measurement won’t be limited by the measurement space

Wide spectral response range

The LS133 has a wide spectral range between 365nm and 405nm, and the response intensity of the 365nm source is almost the same as 375nm, 385nm, 395nm and 405nm

Record the UV power, UV energy intensity, test temperature and curing time together

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

High temperature resistance

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

Without high temperature cover
With high temperature cover

Two measurement modes available

There are two measurement modes. One is Manual mode which needs to start up or end of measurement manually and can be used in most measurement occasions. Another is automatic modes that can automatic switch-on or end of measurement when the energy intensity emitted by the light source is above or below the trigger threshold that can be set. This mode is suitable for occasions where the instrument needs to run for a long time with the conveyor belt to receive ultraviolet rays
