Battery powered dual input manometer with USB output, 
includes USB cable and software
Omega's HHP886 Series 
manometers feature a dual pressure 
input (P1 and P2) and a dual display 
which can be set to simultaneously 
display P1 and P2 or P1 and the 
differential pressure (P1 - P2). 
Pressure is displayed in one of four 
user selectable units and a record 
function will store the MAX, MIN, 
MAX-MIN and AVG pressure for 
each channel for later viewing. 
Models are also available with a 
USB connection for real time data 
logging to a computer. Software 
allows the user to display the data 
in a graphical format or export the 
data to Excel or text files for further 
manipulation.
