Murakami Color Research Laboratory
HM-150 Hazemeter

back to Murakami overview page

The HM-150 measures haze using a double-beam configuration, allowing very high accuracy and good repeatability of measurment.

The lights source is halogen, but near-D65 illumination can be realized by the automatic insertion of daylight filter into the optical pathway. Without the filter, the halogen bulb simulates CIE illuminant A.

A PC is used for the calculation and instrument control for automatic and easy measurement. The functions, including all haze calculations and automatic averaging, are provided with the included software.
The HM-150 Hazemeter is compliant with haze transmittance standards ISO 13468, JIS K 7361
ISO 14782, JIS K 7136 (ASTM D 1003, JIS K 7105)
