Linshang LS335 Touchscreen Spectral Illuminance Meter

Product Highlights

1. Full-Color Touchscreen Display
LS335 Spectral Illuminance Meter Start measuring immediately after powering on. The intuitive touchscreen allows direct operation with no learning curve—say goodbye to complicated buttons and menu systems.

2. Multi-Parameter Measurement
Capable of simultaneously measuring illuminance, spectral distribution, color temperature, color rendering index (CRI), color tolerance, flicker frequency, flicker modulation, blue-light hazard ratio, UV index, temperature, humidity, and more.Suitable for use in various environments and greatly improves testing efficiency.

3. Plant Lighting PPFD Measurement
Equipped with a professional plant-lighting mode to measure PPFD (Photosynthetic Photon Flux Density), YPFD (Yield Photon Flux Density), blue/green/red spectrum PPFD, chlorophyll A/B content, as well as temperature and humidity.Provides accurate data for plant-lighting analysis.

4. Spectral Curve Display
During measurement, the instrument displays the luminaire’s spectral graph in real time, helping users quickly identify whether the light source is full-spectrum LED and whether it is designed with blue-light protection.

5. Color Rendering Index (CRI) Measurement
Used to evaluate how accurately a light source reproduces the true colors of objects. Light sources with high CRI make colors appear more natural and vivid.

6. Correlated Color Temperature (CCT) Measurement
Color temperature determines whether the light feels warm or cool, significantly affecting ambience and visual comfort.This feature is valuable for lighting manufacturers during product development and lighting design.

7. Wide Measurement Range for Both Low and High Light Levels
With a measurement range of up to 1,000,000 lux, the LS335 Spectral Illuminance Meter accurately detects everything from extremely low-light environments to intense illumination, meeting the requirements of diverse applications.

8. High Accuracy and Calibration-Ready
Advanced digital sensor technology and a high-precision spectral sensor design ensure that the probe is resistant to interference and maintains accurate measurements across different light colors.This guarantees compliance with national metrology institute calibration standards.
