Feature

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

Four interfaces help you record the data of UV light source

There are four interfaces to help you know better about UV light source you tested: In maximum values interface, you can acquire cumulative energy value, maxiumum power value and maximum temperature value. Measurement time can be recorded in RT interface. In temperature and power curve interface, you can know the temperature change and energy intensity variation of the light source. Four interfaces can be switched freely

Wide spectral response range

With wide spectral response range, the UV power puck can test UV LED light source with any peak in the range of 365nm-405nm

Powerful PC software

The LS128 UV Energy Meter can be connected to PC software, which allows you to generate reports and print out test results, as well as to export test data

Temperature measurement possible

The high-precision and fast-response temperature detector is used to measure the actual temperature in the curing machine

FAQ

  1. 1. The difference between LS120 and LS128 UV energy meters

    LS120 UV energy meter is mainly used to detect 365nm UV high pressure mercury lamp, while LS128 UV energy meter is mainly used to detect 365nm, 385nm, 395nm and 405nm UV LED light sources.

  2. 2. The difference between LS128 and LS131 UV energy meters

    Both LS128 and LS131 are UV energy meters used to detect 365nm, 385nm, 395nm and 405nm UV LED light sources. They can measure the power value (irradiation intensity) of the UV lamp, the energy value and display the power curve; in addition, LS128 can also measure the temperature in the curing machine, and display temperature curve, but LS131 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.
