The Acustrip Low Levels Metals Test, No. 70003, identifies the level of wear metals in many fluids, including antifreeze coolant, crank case oil and differential oil as well as power steering and transmission fluid. The Low Levels Metals Test was designed for field use, eliminating the need for laboratory work or expensive equipment. Place a sample of the fluid in the provided sample bottle and dip and read the test strip. The test can be used to check for total metals in the fluid as an indicator of wear and corrosion. Not intended for brake fluid, the Low Levels Metals Test is available in a case of 12 bottles of 50 test strips each with a sample bottle.
