The High Precision Series HM35 Digital Manometer is designed to reliably measure and log pressure measurements for critical applications. This family of manometer can measure absolute pressure, differential pressure or gage pressure with up to 0.05% accuracy. The data logging function can store up to 10,742 readings and transmit the readings to a PC through an IR serial port. The large display can graphically display trends in the data as well as peaks and valleys. The series HM35 comes standard with a calibration certificate so that the instrument can be used as a secondary calibration standard when testing other pressure instrumentation. This manometer is ideal for laboratories, calibration facilities, and other critical pressure applications.

For higher accuracy models change the 10th digit from a 3 to a 1 (0.05%

FS), 2 (0.1% FS), or 6 (0.1% of reading). For example, 0 to 28 in of w.c.

with 0.05% accuracy would be model number HM3531DLC100. Higher accuracies are only available on 0 to 28 in of w.c. range or higher.

OPTION

For NIST traceable calibration certificate, use order code NISTCAL-MD.
