Omega's new series of manometers feature dual display and dual pressure inputs. Pressure is displayed in one of four user selectable units (psi, mbar, inH2O, and mmH2O). A protective rubber boot is included with the HHP886 and models are available with a USB connection or wireless interface for real time data logging to a computer. Data logging software is included which allows the user to display the data in a graphical format or export the data to Excel or text files for further manipulation. This CE complaint product is ideal for automotive, HVAC, and R&D/lab use.
