Meriam’s M200 smart manometer line offers NIST-traceable accuracy to ±0.025% FS, including all affects of linearity, repeatability, hysteresis and temperature over the operating range of -4º to +122º F (-20º to +50º C). Recent improvements have added two differential pressure ranges (including a new 0 to 10.000” H2O range), four gauge pressure ranges (now up to 3,000 PSIG) and two absolute pressure ranges (now to 1000 PSIA).
Meriam has also added eight compound pressure ranges to accurately measure ±15 PSIG through -15 to +3000 PSIG. The update increases the number of M200 sensor types/ranges offered from nine to 24. Standard features of the M200 include back light, alkaline battery power, NIST traceable certificate of calibration complete with data, timed leak test, record mode, damping, minimum/maximum value capture and field recalibration support. Options include Intrinsic Safety (ATEX, cULus), carrying case and carrying case with pressure or vacuum pumps.
For wet /wet differential, Meriam offers the M200-DI line with similar performance in five ranges covering zero to 500 PSID measurement at up to 1,000 PSIG common mode pressure. Optional flushing ports with plugs are available for venting trapped gas, cleaning with appropriate solvents or flushing particulates out with water. The M200 is part of Meriam’s line of handheld and field mounted pressure instruments for measurement of gauge, compound, differential (dry and wet), absolute or vacuum pressure.
