PCE Instruments Haze Meter / Colorimeter - PCE-CHM-700

Haze Meter with full spectrum LED light source / Turbidity, clarity, transmission & colour difference / Internal memory / QC test / Spectral curve display / Horizontal & vertical use / USB-C & software

The Haze Meter is ideal for the precise measurement of turbidity, transmission, clarity, color difference and Pt-Co for various transparent and semi-transparent materials such as plastic, glass, films and liquids. It is widely used in material testing, quality control and purity and color monitoring in industry and research.

The Haze measuring device uses a full spectrum LED light source and a high-resolution spectral sensor that measures in the wavelength range from 400 ... 700 nm in 10 nm steps. This enables the Colorimeter to provide a detailed spectral curve representation of light transmission, which can be used to precisely determine the transmission performance of materials and evaluate their optical properties and material color. The color spaces CIE Lab, CIE LCh and Yxy as well as the standard light sources CIE-A, CIE-C and CIE-D65 are supported, ensuring standard-compliant measurements in accordance with ASTM and ISO standards.

Haze measurement is a method for determining the haze of a material - typically plastics, glass, films or liquids. "Haze" describes the proportion of light that does not pass directly through a material but is scattered instead. The result is a milky, blurred effect - the material appears less clear.

With two variable apertures of 14 mm and 5 mm, the transmission meter can measure samples of different sizes, while two measurement modes, horizontal and vertical, offer flexible application options for liquids and solids. For the vertical measurement of liquids, the use of cuvettes with the dimensions 50 × 50 × 10 mm (H × W × D) is required; these are not included in the scope of delivery. The measuring geometry D/0° and observer angles of 2° and 10° enable precise and reliable analyses. The Colorimeter has an internal memory for up to 1000 data sets, a PC interface with USB-C connection and PC software for data export and report generation.

For user-friendly operation, the Haze Meter is equipped with a clear 7-inch color touchscreen for intuitive control. A self-developed adjustment algorithm in combination with the spectral sensor ensures particularly stable and precise measurement results. In addition, the Haze measuring device offers an integrated QC test function, with which predefined tolerance ranges can be checked and deviations detected immediately - ideal for standardized test processes and efficient quality controls. The transmission measuring device is therefore a reliable solution for industrial quality controls, laboratory analyses and research applications that require the highest accuracy and flexibility when measuring optical properties.
