This equipment measure the roughness / smoothness as per the condition apply in the printing press nip at the moment of printing, by clamping the sample between a precise measuring head and a specially Sacking assembly with variable clamping pressure. Ideally suitable for writing, printing /Coated paper and board. The micrometer values measure directly on calibrated Variable Area Flow Meters (Rotameters/digital Panel Meter)
A. Rotameter Model: (Variable Area Flow Meter) Measuring Range: 0.9-6.0 (Micrometers)
B. Digital Model (Microcontroller Based): Measuring Range: 0.6 - 6.0 u (Micrometers)
