M200 smart manometers from Meriam Process Technologies, Cleveland, OH, now include 2 differential pressure ranges, including an 0–10.000 in.H2O range; 4 gauge pressure ranges up to 3000 psig; and 2 absolute pressure ranges to 1000 psia. Eight compound pressure ranges are from ±15 psig through –15 to 3000 psig. Standard features include a backlight, alkaline battery power, NIST-traceable certificates of calibration, and NIST-traceable accuracy to ±0.025% F.S. including linearity, repeatability, hysteresis, and temperature over the –20°C to 50°C operating temperature range. The M200-DI line covers wet-wet differential pressure measurements from 0–500 psid at up to 1000 psig common-mode pressure.
