HAM-300 High Accuracy Spectral Haze Meter

  • Description
  • Parameter
  • Application

HAM-300 is mainly applied to measure total transmittance, diffuse transmittance, haze, parallel transmittance, spectral transmittance and color parameters of automotive front windshield and side window glass transmittance test, etc.).It conforms to the requirements of ASTM D1003, GB/T 2410, ISO14782, JIS K7136, JC/T2130-2013, JIS K7105-81 and other standards.

Ø Main characteristics
●The high precision spectrometer with high quality grating and TE-cooled array CCD ensures high sensitivity and stability.

●Integrated design and simple operation;

●The built-in integral sphere uses the unique SPEKTRON coating of EVERFINE,more stable and longer life;.

●No spectral mismatch errors, it is specially suitable for high precision measurement of any color.

●Spectral measurement range: 380nm~780nm (can be customized).
