Features [Double scale] This pressure gauge is a 2 inch dial instrument with double scale - PSI / Bar, a great pressure measuring tool with stable performance. [Size] This Vacuum pressure gauge dial size: 2", Accuracy: +/- 4/3/4%, Scale: Dual Scale - PSI / Bar, Normal Ambient Temp.: -4F to +140F (-20C to +60C). [Advantage] Water pressure gauge use Glycerin oil filled to enhance the reliability and integrity; helps dampen the effect of vibration and pulsation; lubricates the movement and extends the life of gauge. [Easy to read] Mini pressure gauge features transparent dial cover and clear numeral readings, convenient for clear and accurate readings. Metal outer case for better protection of the internal components, corrosion resistance. [Wide applications] Fuel pressure gauge is used to measure the pressure of a gas or liquid inside a vessel and, often, to help ensure the optimal amount of pressure for a given application. Mechanical pressure gauge is suitable for air, water, oil and other materials that are not corrosive to brass. Specification:Color: Black Package list:1 x Tool Bag1 x Waist Strap Package List
