Fowler 52-174-224 Chrome Plated Twin Beam Dial Height Gage, 24" Max Measuring, 0.001" Graduation

The Fowler 52-174-224 is twin-beam height gauge with a dial gauge, resettable up/down counters, hand-operated feed wheel, a carbide-tipped scriber, a rust-resistant satin chrome finish, a measurement range of 0 to 24", and is precise to 0.001". The dial gauge has distinct, easily read figures for precise measurement. Two separate digit counters register upward and downward travel. Zero setting capability resets to zero or any reference figure at any point for easy reading without special calculations. The gauge is lowered and raised smoothly and evenly on the dual beams by a hand-operated feed wheel with coarse and fine adjustment. Coarse readings are in 0.100" graduations; fine readings are in 0.001" graduations. The included scriber, used to mark position on the workpiece, is carbide-tipped for hardness and durability. The satin chrome finish on the scales resists rust and is glare-free. The base is ergonomically shaped for ease of handling and is hardened, ground, and lapped for maximum flatness.

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 Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
