Available to an accuracy level
+/-0.025% of Full Scale (Model 351)   

Meriam Instrument's 350 Series Smart Manometers are
the first pressure measuring instruments with accuracy
of  +/-0.025% of F.S. at truly low prices. They are
microprocessor-based pressure sensing devices that can
measure gauge, differential, absolute or vacuum pressure.
The displays can read out in any of eleven engineering units
and can also be scaled to special user units for pressure.
Differential models offer a flow function to display
square root flow rate in user defined units. An adjustable damping
feature minimizes the effects of pulsating pressures. A Min/Max
function captures the extremes of pulsating or other varying
pressure signals and a Hold button can freeze the display at
any point of interest.
