Whiteness and chromaticity tester LWACT-A10

Whiteness and chromaticity tester LWACT-A10

Whiteness and chromaticity tester LWACT-A10 is based on a D/0 geometry with a 150 mm diffuser and a 30 mm test aperture, ensuring uniform illumination. It offers excellent stability of less than equal to 0.1 within 30 minutes for high-precision applications. This system supports measurements in both CIE and Hunter color systems (L, A, b), offering versatility for various industry standards. It is a reliable tool for industries requiring meticulous color and whiteness control.

Models of Paper Testing Instruments

Labtron Paper Testing Instruments requires air supply for automatic clamping, ensuring smooth and secure operation. These provide real-time pressure curve displays, allowing users to monitor pressure changes instantly. Their over-range reset function protects the sensor by automatically adjusting it in case of excessive readings. They measure ink absorption values, useful for quality control in printing processes. Our paper testing instruments measure WH Hunter whiteness, YI yellowness, and CIE whiteness for precise color and whiteness evaluations for various applications.
