Starrett 3751AZ-6/150 Electronic Height Gage

The Starrett 3751AZ-6/150 is an electronic height gauge with fine adjustment thumb roll, slide lock, a steel scriber, a hardened stainless steel bar, a measurement range of 0 to 6" (150mm), and a high-contrast LCD digital readout precise to 0.0005" (0.01mm) with + or – 0.001" (0.03mm) of accuracy. The LCD characters are 0.32" high for ease of reading. A fine adjustment thumb roll provides precision measurements. A lock holds the slide in position. The included scriber, used to mark position on the workpiece, is steel for hardness and durability. The round nose of the scriber cuts clean, sharp lines with smoothness and less pressure and can reference zero from the bottom of the base to get the full usable range. The gauge provides the ability to set a temporary zero position and return to a true zero reading. The bar is hardened, stainless steel for durability and is back from the edge of the nose for stability. The base is hardened, ground, and lapped with finger grooves for a comfortable hand grip and ease of movement. The gauge is powered by one 3V CR 2032 battery (included). An auto power-off feature turns the gauge off after 5 minutes of inactivity to extend battery life. The gauge can measure depth of holes, slots, and recesses with the PT08680A depth attachment (sold separately). The gauge comes with the scriber, battery, and an aluminum case.

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.

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
