Product Features U-tube manometer with red or green color concentrate measures positive, negative, and differential pressure for determining velocity and static pressures, leakage, fan and blower efficiency, filter resistance, and gas pressures Columns composed of 1/8" outside diameter flexible and shatterproof clear butyrate tubing for use with water, red fluid, or mercury (sold separately) Choice of calibration in inH2O or mmH2O using water for use with fluorescein green concentrate or mercury (sold separately), or red gauge fluid Choice of measuring range with 1/10 inH2O (2mmH2O on metric units) graduations silkscreened in jet black on stark white scale to ease reading Includes one bottle of red or green gauge fluid Description Dwyer 1222 series Flex-Tube U-tube type manometer uses red gauge fluid, or mercury or green color concentrate to provide positive, negative, and differential pressure measurement for determining velocity and static pressures, leakage, fan and blower efficiency, filter resistance, and gas pressures. The columns are composed of 1/8" outside diameter flexible and shatterproof clear butyrate tubing for use with colored water, red fluid, or mercury (sold separately). The manometer is calibrated in inH2O or mmH2O using water and is available in W/M-style for use with fluorescein green concentrate or mercury (sold separately), or D-style for use with red gauge fluid. The water column has 1/10" divisions for inch scales or 2mm for metric units. Units are silkscreened in black on a white background to ease reading. The manometer has magnetic clips to mount on vertical surfaces and a clamp bar to prevent slipping. Magnets are removable to customize mounting. The manometer includes a bottle of fluorescein green or red gauge fluid.

Manometers measure the pressure of a liquid or gas. They are used in laboratory, medical equipment, engineering, automotive, and heating, ventilation, and air-conditioning applications. Manometers measure any combination of gauge, absolute, or differential pressures. Gauge pressure is the amount of pressure in a system relative to the ambient pressure, absolute pressure is the amount of pressure in a system relative to an absolute vacuum, and differential pressure is the difference between two pressures. Analog manometers are composed of columns of liquid, and they use gravity and the liquid's density to calculate pressure. Because they have no moving parts, analog manometers do not require re-calibration. Digital manometers have pressure sensors that are connected to a system with a hose to provide a digital readout of the amount of pressure present in a system. They use microprocessors to calculate pressure, and they require periodic calibration to help ensure accuracy. Dwyer Instruments manufactures measurement and control instruments, including pressure gauges, flow meters, level instrumentation, temperature instrumentation, and air quality monitors. The company, founded in 1931, is headquartered in Michigan City, IN. What's in the Box?
