ISO 9050 Building Glass Visible Light Transmittance Shading Coefficient Tester Glass Direct Solar Transmittance Testing Machine

LONROY ISO 9050 Building Glass Visible Light Transmittance Shading Coefficient Tester Glass Direct Solar Transmittance Testing Machine

Introduction

The LR-D710 model is suitable for energy efficiency testing of architectural glass, capable of measuring optical and thermal parameters such as visible light transmittance, direct solar transmittance, total solar transmittance, and shading coefficient. It complies with the new national standard GB/T 2680-2021 "Determination of Visible Light Transmittance, Direct Solar Transmittance, Total Solar Transmittance, Ultraviolet Transmittance, and Related Window Glass Parameters."

Instrument Features  

Testing Software: Equipped with Chinese-language software for architectural glass measurement, capable of automatically detecting parameters such as visible light transmittance, total solar energy transmittance, and shading coefficient for architectural glass.

The Chinese software for architectural glass measurement enables functions such as automatic instrument reset, measurement parameter setup, spectral data processing, data export (in text and Excel formats), and test report printing.

Light source: Uses domestically produced light sources, offering higher cost performance.

Detector: High-performance domestic detectors are used for the ultraviolet/visible range; imported detectors are employed for the near-infrared range, offering better cost-effectiveness.

Optical system: Designed with a dual-beam, dual-grating, and dual-detector configuration, reducing background interference and improving measurement accuracy.

Control system: Utilizes a computer for automatic instrument control, automatic calibration upon startup, and automated data acquisition and processing. Dedicated to specific equipment, ensuring ease of management.

Communication interface: Uses USB 2.0 for fast communication, enabling scanning in just 5 minutes per session.
