U Tube and Digital Manometers


We stock a versatile selection of digital and u-tube manometers for the measurement of liquid or gas pressure. Digital manometers are built with sensors for absolute, vacuum, gauge, or differential measurement. Many of our smart manometers also feature a microprocessor, as well as outputs for process control and data transfer. A U-tube manometer is a basic analog instrument that gets its name from its u-shaped tube. The U-tube measures pressure based on the height of a column of liquid. It has a simple design that supports accuracy. From Meriam to Extech, we offer the elite smart instruments for pressure measurement.



Selecting the Right Manometer for Your Media


We have the handheld digital manometers that are built for field calibration, monitoring or troubleshooting. Digital manometer specifications and characteristics include: accuracy, pressure ranges, engineering units, media compatibility, display type, and operating temperature. A digital pressure measurement device can offer specialized features, such as adjustable damping, leak testing, data recording, and hold functions. Advanced manometer packages may include software, connection hoses and other accessories. When viewing U-tube products, you will see pressure range, scale type and construction specifications to consider.


Buy Calibrated Manometers to Reduce Your Downtime


Because Transcat operates dozens of ISO 17025 Accredited Calibration Labs across the United States and Canada, we are uniquely positioned to offer new instrument calibration services on most of the items we distribute.  If your quality system requires that your instruments have a valid calibration certificate at all times, take advantage of our manometer calibration capabilities so that your instrument arrives ready to be put into use.


The Most Reliable Manomters


Meriam’s M2 Series of smart manometers offer superior precision with an accuracy rating of + 0.025% of full scale. The brand’s U-tube manometer in an aluminum frame serves as a primary standard of pressure measurement. Meriam also provides handheld devices for high accuracy during wet/wet differential applications. Extech excels in designing a low range/high resolution gauge with an integrated USB. Amprobe builds manometers for pneumatic control applications, while Dwyer Instruments Mark III digital manometers helps engineers and technicians measure the positive, negative or differential pressures of air and natural gas.
