A thin metal strip, of various cross-sectional shapes, having graduations on one end and must have a cap on the opposite end, and may have a handle. It is designed to be inserted into an engine, pump, or compressor crankcase, transmission, gearcase, fuel tank, or the like, to determine the level of the liquid. For items with an integral breather, see gage rod-breather, liquid level and items without a cap or breather, see gage rod, liquid level.
