Feature

Record UV power, energy and curing time together

It can detect the intensity and energy of UV LED light source at the same time. It has rich statistical functions and can display the real-time power value, maximum power value, energy value and measurement time at the same time

Power curve diagram helps you better understand the operating conditions of light source

The LS131 UV energy meter has a power curve diagram, which can analyze the light intensity distribution of the UV light source through the power curve diagram

Multiple high temperature protection barriers

High temperature resistant design makes LS131 run in the environment of 100 degrees Celsius for a long time. We also provide high temperature resistant protective cover for customers to choose (high temperature cover is not included as standard). The method of using high temperature cover is shown in the figure below. For the detailed process and conclusion of the high temperature resistance experiment of the Linshang UV energy meter, you can click the article below to see the details "Use Time of Linshang UV Energy Meter at Different High Temperature"

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

Offer free PC software

The factory provides free computer software to support the connection to a computer, generate and print reports of the test, as well as export data

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

The probe and screen of LS131 are onthesameside, making it easy to read data

Wide spectral response

LS131 UV Energy Meter 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

The stored data will not lost when the power is turned off

High-speed acquisition of 2048 times/sec makes the test data more accurate

The instrument has a built-in large-capacity memory, which can record up to 60,000 pieces of power data

FAQ

  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 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.
