Adopting a high-level double beam method! This measuring instrument allows for easy high-precision measurements with good reproducibility up to the second decimal place!
The HM-150N is a measuring device that provides the total light transmittance, diffuse light transmittance, and haze (cloudiness value) of transparent objects such as plastics (sheets, films), glass, and liquids. By adopting an F-type double beam method, it eliminates the need for sample movement to the compensating aperture for correcting the integrating sphere efficiency, allowing for user-friendly operation and high-precision measurements. 【Features】 ● Excellent operability and high-precision measurements ● Improved measurement accuracy to two decimal places compared to previous models due to board enhancements ● No instrument deviation from the previous model (HM-150) ● Fully automatic operation with software capable of various calculations, including averaging, providing consistently stable measurement results (requires commercially available computer) ● Vertical model available for large samples (HM-150L2N) depending on sample size ● Wide range of custom specifications available ● Optional ND filters and haze standard plates for linearity verification are also available *For more details, please refer to the catalog or feel free to contact us.

Company information
In 1947, a color research group was established in a corner of Tsukishima, Tokyo, which later became the Color Division of Japan Electronic Measuring Instruments Co., Ltd. The group focused primarily on the production of standard color samples and research and guidance on color adjustment. In November 1956, it became independent and was established as Murakami Color Technology Research Institute, Inc. Since its founding, our company has made the production of measuring instruments related to visual information processing, including "color and gloss," the production of color samples, and the promotion of color management the pillars of our business, and we have been active as a pioneer in the industry. Our market share is extremely high. We will continue to make further efforts for the development of color science and the creation of a prosperous society, and we hope to be of service to everyone.
