SERIES HM35
PRECISION DIGITAL PRESSURE MANOMETER
Up to 0.05% Accuracy, Graphical Display, Data Logging Capability
CALIBRATION SERVICES AVAILABLE
TEST, ADJUST, & BALANCE
The Series HM35 Precision Digital Pressure Manometer is designed to reliably
measure and log 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.
BENEFITS/FEATURES
• Able to record up to 10,742 readings, which can be downloaded to a PC
• Up to 0.05% accuracy for use in critical applications
• Measure absolute, differential, or gage pressure

Note: 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); higher accuracies are only available on 0
to 28 in of w.c. range or higher.
