Clear Reading: Equipped with a 4.5-inch large dial and clear black single-scale PSI markings, paired with a fan-shaped adjustable aluminum pointer for intuitive reading; a stop pin is set at the origin of the dial to effectively prevent damage caused by excessive pointer deflection. The measurement range covers 0-160PSI, meeting the pressure detection needs of various scenarios. Standard Fitting: Adopts a 1/4 NPT radial fitting made of lead-free copper, complying with industrial environmental standards. It features excellent corrosion resistance and strong sealing performance, and is compatible with most industrial pipeline connections. Durable Components: Built-in copper bourdon tube as the core of pressure sensing, with excellent material toughness. It can withstand frequent pressure fluctuations and ensure stable measurement during long-term use. High-Precision Measurement: The full-scale measurement accuracy reaches 1.0%, far exceeding the accuracy level of ordinary pressure gauges. The data is accurate and reliable, suitable for pressure measurement scenarios such as industry, auto repair, and plumbing. Sturdy Case Design: The case is made of 304 polished stainless steel, which is rust and wear resistant; paired with a flat polycarbonate dial cover that is impact and scratch resistant; the back of the case is fixed with stainless steel screws, ensuring firm assembly and adaptation to complex working environments.
