LS120 UV Energy Meter

LS120 UV Energy Meter


I. LS120 UV Energy Meter Introduction

      LS120 UV energy meter is a Chinese famous UV energy meter that can measure energy, power, temperature, time at the same time. The UV power puck can display the energy and power curves, export data and print test report. This "guaranteed product" can be directly comparable to the American EIT UV energy meter and the Japanese ORC UV energy meter dedicated to mercury lamp. The LS120 UV energy meter has created many firsts in the UV energy meter industry:

● The first UV energy meter that can display the temperature curve

● The first UV energy meter can measure real-time temperature and power 

● The first UV energy meter with a built-in timer that accurately records the curing time

● The first UV energy meter that can print a test report via a USB connection to a computer

3.High-accuracy and fast-response temperature detector, truly dynamic measurement of the actual temperature in the curing machine.

4.Built-in heat shield, high temperature resistant design. The UV energy meter can run in the environment of 100 degrees Celsius for a long time. For details on the high-temperature resistance experiments of the Linshang UV energy meter, you can click the article below to check "Use Time of Linshang UV Energy Meter at Different High Temperature". 

5.Built-in large-capacity memory.

6.Built-in timer can accurately record the UV curing time.

7.2048 times / second high-speed data acquisition, the measurement data is more accurate.

8.Two measurement modes, automatic measurement mode and manual mode, suitable for various detection environments

9.The stored data will not be lost when the power is turned off. The last test data will be displayed automatically when the power is turned on. You need to manually delete the test data.
