Differential pressure gauge Clear, easytoread markings combined with a watertype manometer design provide quick, reliable differential pressure readings. This instrument also functions as a pressure test gauge tool for routine checks and diagnostics. Pressure gauge A molded scale curved to fit pipe and fluid contours allows precise readings in constrained spaces. Features an adjustable zero setting for calibration flexibility and serves as a gas pressure manometer in various applications. Manometer gas pressure tester The unit can be mounted on any vertical surface, and its builtin level simplifies leveling to ensure accurate measurements. The Ushaped pressure gauge design enhances stability and readability for gas pressure testing. Stainless steel pressure gauge Made from stainless steel with a Ushaped manometer configuration, suitable for use in air velocity measurements and other generalpurpose tasks. This Utube manometer is designed for durability and versatile performance. Use scenarios HVAC and air filtration: monitor differential pressure across filters or ducts to verify airflow and detect clogging or fan issues. Gas line testing and field service: measure gas pressure in installations or labs, with reliable leveling and stable readings from the Ushaped design. General purpose monitoring: use in industrial settings for air velocity assessments and other applications that require accurate, durable pressure measurements.
