Even outside the valve, the gauge continues to show the last measurement until the user decides to reset it via the reset valve. The pressure gauge was made in accordance with the international standard ANSI B 40.1 Grade B. Accuracy class ± 3-2-3% of the range. An easy to read 1.5 inch [38 mm] dial of the pressure gauge facilitates accurate reading. The pressure gauge is a useful tool that will be a valuable addition to any toolkit.
