LS130 is a UV energy meter that measures both UV energy and UV intensity. It is suitable for testing UV intensity and energy in light sources such as high-pressure mercury lamps and halogen lamps. It is recommended for use in UV curing machine, printing machine, exposure machine, UV dryer and other equipment.

  • A Chinese UV energy meter which ensure to pass the detection by the Chinese National Metrology Institute

  • An UV light integrator for simultaneous measurement of UV energy and UV intensity

  • Simultaneously display real-time power value, maximum power value, energy value and measurement time

  • An UV energy meter that can read data and graphs through special computer software and print test reports

If you need to test the high pressure mercury lamp, you can watch the video below:

Measure the UV power and energy emitted by the light source together

LS130 UV energy meter can measure UV power and energy at the same time. The meter can display real-time power value, maximum power value, energy value and measurement time. The measurement time can accurately show the UV curing time

Two measurement modes available

There are two measurement modes. One is Manual mode which needs to start up or end of measurement manually. 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

Multiple high temperature protection barriers

Adopting metal shell and high temperature resistant design, the UV light integrator can run in the environment of 100 degrees Celsius for a long time. In addition, the instrument also provides a high temperature cover for users to choose. (the high temperature cover is not included as standard)

Offer free computer software

LS130 UV energy meter offers complimentary computer software that can be is connected through a USB interface. You can read detailed test data and print a test report when using software

Large LCD screen can display useful power curves

The large liquid crystal screen directly displays the power curve. The power curve can be used to analyze the intensity distribution of the light source. The front detector design facilitates the reading of data

LCD screen faces up during tests, making it easy to read the data

The detector is located on the same side of the screen and we can read data during the test

Fast-speed data collection at 2048 times/sec to make the measurement data more accurate

The instrument has a large data storage capacity and record the curing time accurately

Automatically display the last test data after powering on to avoid data loss due to power failure

  1. 1. The difference between LS130 and LS131 UV energy meters

    LS130 UV energy meter is mainly used to detect 365nm UV high pressure mercury lamp, while LS131 UV energy meter is mainly used to detect 365nm, 385nm, 395nm and 405nm UV LED light sources.

  2. 2. The difference between LS120 and LS130 UV energy meters

    Both LS120 and LS130 are UV energy meters used to detect 365nm high pressure mercury lamps. They can measure the power value (irradiation intensity) of the UV lamp, the energy value and display the power curve; in addition, LS120 can also measure the temperature in the curing machine and display temperature curve, but LS130 does not have this function.

  3. 3. Whether a traceable calibration certificate is included?

    LS120 and LS130 are professional UV energy meters used to detect 365nm high-pressure mercury lamps, which can be ensured to pass the inspection of the Metrology Institute and obtain a calibration certificate (approved by CNAS and ilac-MRA). The cost of the calibration certificate is about US$200 ; LS128 and LS131 are UV energy meters that are professionally used to detect UV LED light sources. There is no unified inspection standard for LED light sources, each light source and UV energy meter manufacturer has their own calibration standards. We can provide the factory calibration reports for these two UV LED energy meters, but no calibration certificates can be provided.

    LS130 and LS131 have certified to CE.

  4. 4. How to calibrate UV energy meter, how often do I need to calibrate and how much does it cost?

    To calibrate the UV energy meter, please send the instrument back to the manufacturer. Generally, it is recommended to calibrate it once a year. If the storage environment is good and the frequency of use is not high, the calibration period can also be extended according to user needs. The first calibration is free, and the cost of each subsequent calibration is US $32.
