【Precise measurement】Inclined - vertical tube design, large measurement range, low reading easy to read, measurement accuracy ±3%, supports positive and negative pressure, differential pressure measurement.
【Durable and reliable】Leakproof O-ring seals and overflow tank reduces risk of fluid loss. It can be mounted on any vertical surface and built-in spirit level simplifies leveling.
【Wide application】Inclined-vertical manometer for use in air velocity and air filter performance applications, and other general purpose applications in determining the timing of filter replacement.
【Environmental adaptation】The red anti-freezing pressure gauge fluid has a low evaporation rate, making it suitable for cold environments. Expanding the scale enhances the reading resolution.
