Meriam Process Technologies’ M200 Smart Manometer line added several pressure ranges and a new offering of compound pressure ranges. The line offers NIST-traceable accuracy of +/-0.025 percent (full scale), including all effects of linearity, repeatability, hysteresis and temperature over an operating range of -4 F to 122 F (-20 C to 50 C). Recent improvements have added two differential pressure ranges (including a new 0-10.000” H2O range), four gauge pressure ranges (now up to 3000 PSIG), and two absolute pressure ranges (now to 1000 PSIA). The device now also supports eight compound pressure ranges to measure -15 PSIG to 3000 PSIG. The update increases the number of M200 sensor types/ranges offered from 9 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 re-calibration support.
