Fieldpiece Dual-Port Manometer - SDMN5

Product Information

You can use a manometer for numerous applications. Manometers may be used in atmospheric surveys, gas analyses, and weather surveys. They can also be used for medical diagnosing in HVAC and gas grills. The Dwyer 1211 is a differential manometer though it can be used to measure static and vacuum pressure of air and gas. It happens to be affordable compared to digital options, and it is designed to be easy to use and transport.

The HD755 also happens to be a differential manometer, and you can measure the difference in pressure between two points. Connect the tubings to P1 and P2 and should the pressure in P1 be higher than that in P2, it will record a positive reading, and a negative reading should the pressure in P2 be higher than that in P1.In the static pressure mode, the unit can measure up to 2″WC with resolution to 0.010″WC, which enables a technician to measure small differences in air (or static) pressure. Mercury is toxic but still happens to be the preferred fluid in manometers owing to its density. It has a density higher than most fluids and thus is immiscible with most liquids. Moreover, the meniscus is visible and thus taking readings will be a breeze. Other fluids such as CC14 form an opaque layer on the columns which is not the case with mercury. Manometers are for gauging pressure in a fluid or gas column and is used by technicians and professionals in measuring industries. Typically, the device is u-shaped with two graduated legs and have a liquid that will rise anytime pressure acts upon it. The liquid acts such that when the two legs are exposed to the same pressure, the height of the liquid will be the same in both columns. However, should a liquid be applied in the left column, the liquid level on the left falls while that on the right rises until the fluid and the pressure balance. The difference in height is the pressure of the fluid or gas that was in doubt.

Another remarkable feature of the device is the built-in zero lever that allows linear recalibration. It also happens to be portable thanks to the A-612 stand and tubing that can be slipped over the pressure connections containing the gauge fluid while in transit. Testo has been around for more than 60 years having launched in 1957, and you cannot be around for that long by making products that do not work. The Testo 510 is one of the best manometers in the market thanks to its compact size and precision but more on these later. Digital– These are the most common manometers and use a microprocessor and pressure inducer to measure pressure. The pressure transducer serves to sense changing pressure and that appears on the screen. First, their portability sets these devices apart from the rest as you can use without a level surface. Moreover, they are easy to read, they can record data and easily interfaces with computers. What are you going to measure?

One fascinating feature of the gadget is its portability. It is lightweight, and you can carry it and use it in any environment. It can also be used as a differential unit to measure the pressure between two points. Magnet - The magnet on the rear helps in hanging the manometer during service. It is a nifty feature especially for HVACR professionals who when measuring pressure between two points.

Affordability – The low price point of the Rupse is what has made it such a hit. It is a fraction of the cost of other manometers on this list and is great for people on a budget. First, always consider the liquid used in manometers. Often used are water and mercury, but benzene, colored water, and bromides work as well. However, consider the prevalent temp, the vapor and density before purchasing a manometer. Furthermore, you can get a digital or analog manometer. The latter are sturdy and well-built but some calculations are required, and the readings are not easy to take. The revolutionary new JL3KM2 Job Link® System Manometer probes give HVACR pros the freedom to work the way they want to — unrestricted by hoses, so technicians get readings from optimal locations on every system, every time.One fascinating feature of the UEI EM201B is that it measures static pressure in inWC, mBar, PSI, or Pa. You can use the inWC when in the USA and the mBar in other nations such as Canada. Also, it has a maximum reading of 60inWc, unlike the Testo which has a max of 50inWC. You will also appreciate that it is easy to use, and quality housing. The Mark II is great for measuring pressure above and below atmospheric pressure and can measure differential pressure too. Furthermore, the red gauge fluid is freeze proof, and you can use it in cold temperatures. Also, it has a lower evaporation rate enabling you to work in sweltering heat.
