Haze Meter

The YH Series Horizontal Color Haze Meter is an advanced optical instrument designed to precisely measure transmittance, haze and clarity in transparent materials. This model is a High-Precision Haze & Chromaticity Meter.

KEY FEATURES:
Supports ASTM D1003 (non-compensation) and ISO 13468 (compensation) methods.
Measures total transmittance, haze, clarity, and full chromaticity data.
Uses precision concave grating and 256-pixel CMOS array.
Captures detailed spectral transmittance curves.
Best repeatability, highest resolution, and colorimetric accuracy across all models.
