The DHM28-10 is a microprocessor-based precision handheld manometer designed to measure a wide range of pressures to very high accuracy, offering differential, gage, or absolute measurement with selectable scales and display resolution to 0.001 of the selected unit. It stores up to 964 readings, features a two-line liquid crystal display and adjustable auto power off, and can serve as a secondary calibration standard, shipping with a certificate of calibration at no additional cost. The D477AV-0 Dwyer handheld manometer uses a highly accurate differential pressure sensor to provide pressure, flow, and velocity measurements with ±0.5% full scale accuracy. Housed in a rugged aluminum case, the D477AV-0 calculates air velocity and volumetric air flow, offers 9 selectable English and metric units, and stores up to 40 readings with min, max, and average statistics.
