Manometers are compact, portable, digital measurement instruments used across a number of industries and occupations to measure the air pressure, gases pressure or fluids pressure. They’re handheld, battery operated and have clear digital screens so results can be easily read, even in awkward places or in the bright or dim light. Hi-tech sensors and sophisticated microprocessors give highly accurate readings. Many manometers come with software that allows data to be transferred to laptops, smartphones or tablets for storage or analysis.What are digital manometers used for? In commercial, domestic or industrial environments, digital pressure meters are handy tools for carrying out routine pressure tests, for troubleshooting system failures or for seeking out leaks. In refrigeration systems, digital pressure meters can gauge pressure, vacuum and temperature. Alternatively, they can be used to establish flow and static pressure in gas systems, and be used for pressure-drop testing in gas pipes. Digital manometers are suitable for measuring absolute pressure, differential pressure, and gauge pressure. In conjunction with a pitot tube, a manometer can convert pressure readings into air velocity (FPM). Choosing the right digital pressure meters. Your task and environment will influence your choice of digital pressure meter. Other considerations include minimum and maximum pressure measurement requirements, data logging, port size and the meter’s suitability for use in hazardous areas.
