Caliper Thickness Gauge (Dead Weight Type) A precision instrument to accurately measure the thickness of flexible and semi-rigid substrates like : Paper, Paper board, Corrugated fiber boards, Plastic Films, Laminates, Aluminum Foils,       or any other material in sheet form. Definition : Thickness or caliper of paper, paperboard, or combined board as measured by this equipment is defined as the perpendicular distance between the two principal surfaces of the substrate under prescribed conditions, as measured between hard ceramic platens. Significance : Till recently, the most common method of measuring thickness was by using a vernier caliper or micrometer. This form of measurement was not very reliable since the amount of pressure applied by the operator's thumb cannot be quantified or reproduced. Hence, the readings will vary operator to operator. The Dead Weight provided on our Caliper Thickness overcomes this but always providing a constant, impartial, horizontally downward force while clamping the sample between its anvil and the measuring foot. Thereby giving a highly consistent reading with reproducible test conditions. All human errors or operator dependencies are eliminated. The deadweight applies a constant pressure of 500 grams/cm2 as described in TAPPI T - 411. Models available : Various models starting from Economy Analog models to the high-end Fully Automatic Computerized models. This equipment is relevant to : Paper Mills. Carton Manufacturers. Plastic Film manufacturers. Laminators. Printing Units. Heavy End-Users of Paper, Film or Foil. Research Institutions. Packaging Development centers.
