Home/Products/Test Equipment/Manometer Manometer Manometers are portable test equipment that indicate single or differential pressure. Air velocity is measured in some models. Portable Portable manometer test equipment indicates pressure. Applications include filter monitoring, laboratories, fan status, duct static pressure, and field calibration of other instruments. Dwyer's manometers are precision instruments in inclined and vertical styles. Most versatile and useful low cost manometers we know of. Beplay手机app维护 Air Velocity instruments are portable manometers which indicate pressure and air velocity. Dwyer's air velocity models are accurate instruments designed for measurement of low differential pressures in laboratory and test applications. Ideal for measurement of low range gas and air pressures, positive, negative or differential.
