PCE Instruments PCE-CHM 700 Colorimeter

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

The Haze meter uses a full-spectrum LED light source and a high-resolution spectral sensor that operates in the wavelength range of 400 ... 700 nm in 10 nm steps. This allows the spectrophotometer to provide a detailed spectral curve representation of the light transmission, which enables accurate determination of the transmission power of materials and their optical properties as well as material color to be evaluated. The color spaces CIE Lab, CIE LCH and Yxy are supported as well as the standard light sources CIE-A, CIE-C and CIE-D65, whereby standard-compliant measurements are ensured according to ASTM and ISO standards.

Haze measurement is a method for determining the turbidity (haze) of a material – typically in plastics, glass, films or liquids. "Haze" refers to the amount of light that is not passed through directly but is diffused while passing through a material. The result is a milky, blurry effect – the material looks less clear.

With two variable blades of 14 mm and 5 mm, the transmission meter can measure samples of different sizes, while two measurement modes, horizontal and vertical, offer flexible applications for liquids and solids. Vertical measurement of liquids requires the use of 50 × 50 × 10 mm (H × B × T) cuvettes; they are not included. The measurement geometry D/0° and observer angle of 2° and 10° enable precise and reliable analyzes. The spectrophotometer has 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 ease of use, the spectrophotometer has a clear 7-inch color touchscreen that provides intuitive control. A self-developed adjustment algorithm in combination with the spectral sensor ensures particularly stable and precise measurement results. In addition, the Haze meter offers an integrated QC test function that allows pre-defined tolerance ranges to be checked and deviations detected immediately – Ideal for standardized test processes and efficient quality controls. The transmission meter is thus a reliable solution for industrial quality control, laboratory analysis and research applications requiring the highest accuracy and flexibility in measuring optical properties.
