The Grainger G3261 Level Gauge is a 49 inch long high-density polyethylene dipstick designed for measuring liquid levels in tanks and reservoirs. It features easy-to-read black measurement markings every 1/8 inch for precise level indication. This chemical-resistant gauge can withstand temperatures up to 180°F and is suitable for use with water, diesel fuel, solvents, and other liquids. With an overall length of 49 inches, this durable HDPE dipstick provides a wide measurement range for tanks up to 48 inches deep. The flat design allows the gauge to rest evenly on the bottom of a tank for consistent readings. The G3261 helps monitor liquid levels and prevents overfills and spills.
