The Series HM28 Precision Handheld Digital Manometer is designed to measure
a wide range of pressures with up to 0.05% accuracy. The data logging function can
store up to 964 readings and transmit the readings to a PC through an IR serial report.
The dual line LCD is able to display a resolution to 0.001 of the selected unit and
indicate peaks and valleys.
