This document summarizes a precision caliper thickness tester used to measure the thickness of flexible materials like paper, films, and laminates. It has a digital caliper gauge mounted on a base with a dead weight that applies a constant 500g/cm2 pressure. A key feature is its motorized mechanism that lifts and releases the measuring foot in a simple cyclic motion, allowing for fast, reproducible measurements at a rate of 6-10 readings per minute. Models are available with different measurement ranges and resolutions down to 1 micron.

Caliper Thickness Tester (Motorised / Automatic)
(Dead-Weight Type)
This is a precision instrument to accurately measure the thickness of flexible and semi-rigid
substrates like tissue, paper, board, corrugated board, plastic films, laminates, foils, etc.
A Digimatic caliper gauge is mounted on the base with a Dead Weight on top so as to develop a
uniform, reproducible constant pressure on the anvil through the foot.
This model has a special motorised mechanism which lifts and releases the measuring foot in a
simple cyclic motion. This helps the operator to use both of his hands to load and unload the samples
and the user can take 6 - 10 readings per minute. There is also a 3+1 second time delay between the
release-lift action of the measuring foot. This ensures the highest levels of reproducibility and also
confirms to various international standards.
