Manometers Air Pressure Meters

Manometers are devices that measure air pressure. As an instrument, manometers are quite simple, having no moving parts and requiring no calibration to measure and indicate air pressure. Manometers use a small liquid-filled tube to measure air pressure. The tube is U shaped and each edge side is open to the atmosphere. Variations in atmospheric pressure cause fluctuations in the density of the liquid in the tube. These fluctuations show on the instrument and you use those to determine air pressure. Some of the most popular manometers come from HVAC and Dwyer.

Referenced Measurements

You can define manometer measurements as differential measurements. This means that the air pressure value has no reference point. Consumers can use their manometers to determine their own reference point, whether it’s an arbitrary value or vacuum pressure. However, if you need results quickly, digital manometers feature several convenient measure units that you can use to convert units and establish a reliable base value.

Multiple Functions

You can use your manometer in many different applications. Some of the most common functions of a manometer are testing the air pressure of ventilation systems and air conditioning units, monitoring air pressure in a new room or assessing the pressure of a gas system. Whether you have a budding interest in engineering or you need to determine air pressure for a school project, manometers are efficient and accessible scientific instruments.

Durable Design

Digital manometers are easy-to-use and difficult to break. To avoid overheating and conserve battery life, manometers have automatic shut-down procedures when not in use. To further increase the durability of your test equipment, you can encase manometers in extruded aluminium.

Versatile

Because of its lightweight and portable design, you can use your digital manometer in a closed room or exposed to the elements. Collected data is easy to read and interpret via a large backlit LCD screen. For large scale projects, industrial detectors and digital manometers will include data retention buttons, allowing you to store multiple air pressure results. For simple projects, other test detectors, such as low-cost stationary manometer indicators, can be used to determine simple values for positive and negative pressure fluctuations.
