The Fowler 52-174-212-0 is a twin-beam dial height gage with dual resettable up/down counters, hand-operated feed wheel, a carbide-tipped scriber, a rust-resistant satin chrome finish, a measurement range of 0 to 12", and is precise to 0.0015". The dial gage has distinct, easily readable figures for accurate measurement. Two separate digit counters register upward and downward travel with zero setting capability, which resets to zero at any point without particular calculations. The gage is lowered and raised smoothly and evenly on the dual beams by a hand-operated feed wheel with coarse and fine adjustment. It also features a carriage lock lever to hold the measuring head in place while scribing. Fowler, an American company, manufactures premium inspection and measurement instruments like electronic indicators, calipers, bore gages, and micrometers.
