LS332 is a multi-function luminance meter designed with Light spectrum Sensor, which is used for the measurement of luminance, flicker frequency, color rendering index and correlated color temperature in various occasions such as display screens, backlight panels, lamps, etc. The instrument can display Spectral Curve at the same time, and the type of backlight can be identified through Spectral Curve.
1. Support ultra-high luminance measurement, the maximum range is up to 1 million cd/m ², easy to deal with all kinds of bright scenes, such as HDR screens, lamps, projections, etc. 2. Equipped with 10mm and 20mm replaceable Probe light cylinders, large and small screens can be accurately measured, and one machine is more flexible for multiple uses. 3. Support instantaneous measurement, start to measure, the results are displayed immediately, no need to wait, improve work efficiency. 4. The test results are accurate and reliable, in line with the national reliable Measurement Agency testing standards, to meet the needs of professional certification. 5. The instrument adopts Light spectrum Sensor design, Light spectrum Response and V (lambda) function are exactly the same, to ensure that the instrument measurement of various different color temperature screens have accurate measurement accuracy. 6. With stroboscopic measurement function, evaluate whether there are stroboscopic problems in display screens, lamps, etc., and assist eye protection display detection. 7. Through Spectral Curve analysis, the light source type of the display can be identified. 8. Able to measure the color rendering index to help evaluate the color reproduction performance of lamps or display devices. 9. Measurement of the color temperature of the screen or Illuminant to determine whether it meets the industry standard. 10. Using advanced digital Probe technology, digital signal processing is completed directly on Probe, Probe is not easily disturbed and provides excellent test accuracy. 11. It can display the real-time value of luminance, MAX Maximum, MIN Minimum, and average value at the same time, which is convenient for comprehensive control of Illuminant changes. 12. Built-in storage function, can save 9 sets of measurement data, easy to view or compare results at any time. 13. The luminance meter supports connecting to Mini Program or computer software to export measurement results with one click, helping users easily complete data archiving, analysis and sharing.
The instrument adopts the Light spectrum Sensor design, and its Light spectrum Response is exactly the same as the V (lambda) function, which ensures the accuracy of measurement of various color temperature screens. At the same time, the advanced digital Probe technology is used, and the digital signal processing is directly completed on the Probe, which reduces interference and improves the test accuracy.

Step 1 Power on. 2. Select and install the appropriate Probe light cylinder (10mm or 20mm) according to the measurement object. 3. Aim the Probe at the Illuminant or screen to be measured and maintain the appropriate measurement distance (luminance measurement ≤ 1m, flicker frequency measurement ≤ 0.1m). 4. The instrument will instantaneously display the measurement results, including luminance, flicker frequency, color rendering index, correlated color temperature and other parameters and Spectral Curve. 5. View real-time values, MAX Maximum, MIN Minimum, Average, or save measurement data through the instrument. 6. Mini Program or computer software can be connected to export measurement results for archiving, analysis and sharing.
• Please make sure to operate under the specified Operating Environment: temperature (0~ 40) ℃, humidity < 85% RH. • Please pay attention to maintain the specified measurement distance when measuring: luminance measurement distance ≤ 1 meter, flicker frequency measurement distance ≤ 0.1 meters. • According to the size of the object to be measured, select the appropriate Probe light cylinder (φ 10mm or φ 20mm) to ensure the measurement accuracy. • The instrument is powered by 2 AA alkaline dry batteries with a power supply voltage of DC3V. • The instrument has built-in storage function, which can save up to 9 sets of measurement data. Please pay attention to exporting or managing data in time. • Luminance measurement accuracy is ≤ +/- ( 5% H + 2cd/m ²), where H is the standard value (calibrated under CIE standard A Illuminant). The accuracy of the correlated color temperature and color rendering index is also based on specific calibrating conditions, please pay attention to the calibrated state. • Do not use under conditions that exceed the instrument specifications (e.g. luminance, color temperature, flicker frequency range).
Yes. I recommend a multifunctional luminance meter that not only measures brightness but also flicker frequency and color rendering index, helping to evaluate flicker issues and color reproduction performance. It complies with multiple eye protection and lighting design standards, making it well-suited for your professional testing needs.
In addition to brightness, it is recommended to pay attention to flicker, color rendering index (CRI), and color temperature. Flicker measurement can assess whether there are flickering issues, aiding in eye protection testing; the color rendering index helps evaluate color reproduction performance; color temperature measurement can determine whether it meets industry standards. All of these are crucial for the quality assessment of displays and lighting fixtures.
