What is a portable barometer or manometer?

Portable manometer or digital differential manometer is used to measure single inlet pressure or differential pressures (dual inlets) of air and water. Also, digital portable manometer or digital differential manometer is used to measure pressure in different ranges and scales. Used in refrigeration industries, pneumatic and pneumatic systems, etc.
Technical specifications of portable manometers

A portable manometer or digital differential barometer connects to a computer via a USB port, and data is transmitted and analyzed via a USB port.

Portable manometer or digital differential pressure gauge, the ability to display pressure in different ranges and convert the measured pressure values ​​into different units such as bar, mbar, kpa, kgf / cm2, mmHg, cmH2O, Ozf / in2, psi, inHg and inH2O. ftH2O.

Application of portable manometer

Digital manometers or digital differential pressure gauges have a variety of applications, including the following:

Industrial
medical
Laboratory
Heating
air conditioning system
