Digital Micrometer


The NEW model 49-87 Paper Thickness Micrometer combines a precision digital linear encoder measuring system with an ultra-clear, easy-to-read digital display. The unit can measure paper thickness in a range: 0-0.50 in. (0-12.7 mm) and is designed for thick materials such as corrugated, paper board, tissue paper, battery separators, plastic sheets and non-woven The motor-driven instrument utilizes the dead weight micrometer principle for high accuracy and repeatability. Each unit is designed and manufactured for very high precision.

The model 49-87’s construction consists of a heavy, solid frame which supports the unit and houses the reflective linear encoder and associated circuitry. A digital readout is provided to automatically display the specimen thickness. The lower anvil and movable pressure foot are made from lapped, stainless steel.

The unit has the capability of measuring and storing multiple thickness readings, providing a cross machine profile. Up to 100 readings are stored and analyzed including high, low, average and standard deviation for each series of tests. Data can be permanently saved with optional GraphMaster PC-based software or printed.
