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.
