Mahr Federal 816 CL Digital Height Gauge, 14″ Measuring Range, 0.0001″ Resolution, Motorized Carriage

Mahr Federal 816 CL Digital Height Gauge, 14″ Measuring Range, 0.0001″ Resolution, Motorized Carriage


SKU: B00H1WO1UA Category:


The Mahr 816 CL Digimar series height measuring gauge uses optical incremental measurement, with a double-reader head and a dynamic probing system, for accuracy and repeatability and measures in 0.0001″ (0.001mm) increments with a 14″ (350 mm) vertical measuring range. An integrated temperature sensor allows temperature-compensated measurement. It has a motorized carriage for positioning the measuring probe and is programmable for automating repetitive measurement procedures. The gauge has built-in functions for measurement and MarConnect data output for use with USB, RS-232, or Digimatic interfaces. It has a backlit graphic LCD display and a rechargeable battery for up to 14 hours of operating time. This height-measuring gauge has a heavy-duty base for stability and a stainless steel slide with an air-bearing system for smooth movement, and is suitable for use in measuring heights and distances in applications such as quality control of machined parts on a production line.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Height gauges, sometimes referred to as gages, are precision measuring instruments that travel on a vertical column (also called the beam) to measure and/or mark the vertical distance from the base of an object in fine units. The vertical position of the gauge and its attached pointer are changed by turning a calibrated screw, or one or more feed wheels. Recorded rotations are read from a scale, a dial, counters, and/or an electronic display. A screw clamp holds the pointer to the gauge. The pointer is typically sharpened to act as a scriber, and can be used to mark a position on a workpiece by scratching its surface. On compatible units, the scriber may be replaced by an electronic touch-signal probe. Height gauges are typically used in manufacturing, machining, and mechanical engineering.

Mahr Federal manufactures dimensional metrology instruments and metering systems. The company, founded in 1861, is headquartered in Goettingen, Germany.
