Meriam Process Technologies” M2 smart manometer, part of the M Series line of test instruments and calibrators, is the first in a sequence of handheld instruments that are designed to simplify pressure calibration and monitoring. The manometer features a compact, rugged design that makes it a good fit for field applications. Its accuracy allows it to serve as a pressure reference standard.

Features include:
• 11 selectable user units (consult factory for custom user units)
• Expanded ranges to handle gauge, differential, absolute, or vacuum pressure
• Min/Max feature to capture extremes of varying pressure signals
• One-point or five-point field recalibration for zero, span, and linearity
• Leak test procedure to calculate leak rate in units selected per minute
• Flow function to display square-root flow rated in user-defined units
• Custom-molded protective rubber boot
• Polycarbonate enclosure with permanently static dissipative, ESD protection
(6.5” × 3.6” × 2.25”)

Applications include:
• Calibration of field devices (pressure gauges, transmitters, recorders, and switches)
• Pressure drop across filters and rotary vane meters
• Open flow measurement of gas wells with a pitot tube or orifice plate
• Verification of vacuum pumps and barometers
• Pharmaceutical process monitoring (low pressure or vacuum)
