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 or wireless interface 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.

Rated 5 out of 5 by from USB Manometer Very good USB Manometer for the price. Unit was shipped very quickly to our Lab

Rated 3 out of 5 by from Out-of-date software - XP and below It's 2019, and yet the software coming with this manometer doesn't even support up to Windows 7. Was that included in the specs? Nope. How about the manual? Nope. Cost us some hassle. Nevertheless, the manometer itself works fine, as did the software once we got over the annoyance. Hardware: 4 stars Software: 2 stars

does this measure in negative pressure?

Asked by: DanW
Don: Thank you for contacting Omega. Yes, the HHP886 series manometers can measure negative pressure. Each of the two pressure input channels can measure over the range of -60 to +60 Inches of Water. Resolution is 0.01 inches. Please feel free to contact us again if you have any additional questions.

I am new to 'differential pressure' measurement. The spec shows Measurement Range of +/- 2.0000 PSI. Do you never expect to see a differential pressure greater than 2 PSI (~ 150 mBar)?

Asked by: RJS Cali
This specific model is rated for +/- 2 psi, and you may not exceed 2 psi differential on this unit. In case you want to read higher differential pressures we suggest looking at the HHP400 series. In case you need selection help feel free to email us at
