Meriam M200LS-GI0500 Lab Standard Smart Manometer, Gauge Pressure, 0-500 psi Range, + or - 0.01% Accuracy Full Scale, 1/8" NPT Female Connection, Battery Operated
The Meriam M200LS-GI0500 Smart portable digital manometer has a non-isolated differential sensor performs gauge pressure measurements. The meter has a measuring range of 0 to500 psi. NIST traceable accuracy of + or - 0.01% of full scale includes all effects of linearity, repeatability, hysteresis, and temperature from 59 to 86 degrees F (15 to 30 degrees C). The 1/8" female NPT connection is composed of 316L stainless steel and brass parts and has Viton O-rings for use with clean, dry, non-corrosive gases. Engineering units include inches of water, psi, mm of Hg, inches of Hg, mbar, bar, kPa, kg/cm2, cm of H2O, and user-selectable scaling. The meter can be field-recalibrated for zero, span, and linearity with one- or five-point calibration. Leak test feature allows users to view Min/Max pressure values and calculate the leak rate per minute in pressure units when pressure testing pneumatic systems. Exponential damping has a user-selectable time constant from 0.1 to 25 seconds to minimize the effect of pulsating pressures.
The keypad has a sealed membrane to protect the instrument from contamination, and five dome contact-style buttons to ease operation. The two-line LCD shows 5 significant digits, and has contrast adjustment for use in a variety of lighting situations. The two-stage backlight provides visual indication of over-range measurements. The display can read out in any of eleven pressure units, or can be linearly scaled for user-selectable scaling. The meter has a square root flow function to display 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 varying pressure signals, and a Hold function freezes the display at any point of interest. Auto Record retains up to 240 readings for future recall. The meter has automatic shut-off at user-selectable times of 10, 20, 30, 45 or 60 seconds to extend battery life. The polycarbonate case is permanently static dissipative to provide ESD protection. The meter includes a rubber boot to protect against accidental bumps or drops.
