Features
• Portable, battery-operated pressure measuring device
• Measures gauge pressure (a measure of pressure in psi that is refer-
ence to ambient pressure) and differential pressure (a measure of the
difference between two pressures)
• 11 selectable pressure units: bar, mmHg, ozin2, kgcm2, psi, inH2O,
kPa, ftH2O, inHg, cmH2O, mbar
• Primary LCD readout displays currrent pressure reading while sec-
ondary readout displays real time clock
• Not suitable for absolute pressure measurement
