The Meriam ZM200-AI0017-.025 Smart Manometers bring high precision and value to handheld, digital manometer users. The M2 features NIST traceable accuracy of + 0.025% of F.S., independent of temperature effect, at the lowest prices available. Pressure ranges from 0 to 17 PSIA Absolute and can use isolated values of 0-900 mm Hg. This manometer is designed to measure absolute pressures and the display can read out in any of eleven pressure units or can be linearly scaled for special user units. An adjustable damping feature minimizes the effects of pulsating pressures. A Min/Max function captures the extremes of pulsating or varying pressure signals and a Hold function can freeze the display at any point of interest. Auto Record documents up to 240 readings for future recall.
