Omega’s HHP360 is a very high 
accuracy, handheld barometer/ 
absolute pressure meter suitable  
for the most demanding field 
or laboratory conditions. It can 
measure absolute pressure, 
barometric pressure (corrected 
to sea level) or altitude based 
upon sea level or corrected for a 
map or trig marker. Pressure can 
be displayed in 1 of 7 different 
engineering units. Altitude can be 
displayed in either meters or feet. 
The HHP360 Series also has a leak 
test mode to determine the rate of 
leakage in a pneumatic system,  
and data logging, either automatic 
(taking readings every 5 seconds for 
20 minutes) or manual for up to  
240 readings.
