OMEGA’s HHP9303 handheld pressure meter and data logger is suitable for a wide variety of applications. Pressure range is selected by interchangeable remote pressure sensors. Sensors are available in 8 different ranges of 2, 5, 10, 20, 50, 100, 200 and 400 bar.
Recalibration is not required when changing ranges. Pressure can be displayed in one of 10 user selectable pressure scales (bar, psi, Kg/cm2, hPA, kPA, mmHg, inHg, meters H2O, inH2O, Atm).
In addition to displaying real time pressure readings the HHP9303 can log data manually or automatically at any sampling rate from 1 second up to 9 hours. Readings are date and time stamped and stored on standard SD memory cards from 1 to 16 GB storage capacity. A 2 MB SD card in included. The user can remove the card and plug it into a laptop or desktop computer either directly or via a USB card reader. Files are stored with a “.xls” extension so they can be opened with Microsoft Excel without the need for any other software.

Does this use plug in wired pressure transducers where I could use a transducer to measure pressures from a hydraulic pump on a machine

Does the unit read/record negative values (vacuum in in-H20)?

Asked by: Joe San Diego
Thank you for your inquiry, the HHP303 is designed for pressure only

What are the sensors that the unit can read? Do they come with it or are they purchased separately

Asked by: Charlie11
The sensors for HHP9303 would be purchased separately. There are 8 pressure ranges available 0 to 2 bar, 0 to 5 bar, 0 to 10 bar, 0 to 20 bar, 0 to 50 bar, 0 to 100 bar, 0 to 200 bar & 0 to 400 bar. The should be used with clean dry non-corrosive gases only.

What kind of sensor does the HHP9303 take? I need to be able to measure the force of impact of liquid pesticides sprayed on plants. I should be able to spray the sensor with the liquid and read the psi in the range of 80-100 psi.

Asked by: R C Dutton
The HHP9303 will not work for application. The remote plug-in sensors for this unit are limited to use for clean dry non-corrosive gases. Contact our Pressure Application Engineers at for help in choosing a product that would be correct for your application
