MaraMeter Indicating Measuring Instruments for Outside Dimensions 9-31 Mahr Wire Insulation Thickness Gages 57B For checking wall thickness of wire insulation and other small-diameter tubular parts Features 1 Using the basic design of the Model 57B-13 (Model 57B-13M Metric) Gage the lower contact is PT-103 1.10 mm .043" diameter rod mounted horizontally. The upper contact is a flat chisel contact in line with the rod. By slipping tubular parts onto the lower contact the gage can measure the thickness of the wall of the tube. An auxiliary weight on the Indicator provides a total dead-load weight of 25 grams. (Replacement lower rod PS-43) 2057750 Technical Data Order no. Metric Inch 57B-13M 2057550 Options 57B-13 Capacity mm inch 762 0 - .30 PT-2245 Description Dial Indicator readout with 7.6 mm .30" sensitive range and 0.01 mm .0005" grads. 1086 Digital Indicator with 25 mm 1" range and 0.001 mm .00005" resolution. 0.050 mm .02" diameter Pin Lower Contact Assembly Measuring Compressible Materials Compressible materials such as paper plastics rubber or fabrics must be measured under controlled conditions. Many materials have measurement standards specified by A.S.T.M. U.L. or other industry standards organizations. Measurement standards specify dead load weight upper and lower contact configurations and Indicator resolution. Series 57B Gages are easily modified to meet most of these industry standards. Mahr Federal has on file designs for the measurement of paper latex foam rubber sponge rubber vulcanized rubber asbestos tape and cloth sheet and roll felt and many other materials. When inquiring specify A.S.T.M. Specification Number if possible. +
