Best Manometer Reviews 2020

Different types of manometers exist in the market and are available at different prices. The differences in their features and functionality may be responsible for the price range. These factors have to be considered if you are going to spend your hard-earned money getting a manometer.

In order to decide what should be the ideal price for a manometer, we have to eliminate the confusion in the minds of our customers regarding what to look out for. Our buying guide is properly detailed and would help you make the right decision. After much research and consideration, we found out that the best manometers are within the price range of $55 to $164. Yes, we found some rather cheap manometers, which were inadequate in some things like features and portability, so we ignored them (and so should you).

Manometers may come in similar or slightly different designs due to the kind of work they are used for. If you want to pick a manometer, you would have to consider carefully some factors that would ensure you get maximum benefit out of the device. Here are the principal factors to consider:

• Type (U-Tube, micro and inclined-tube manometers)
• Indicator liquid
• Functionality
• Power Source
• Memory
• External casing
• Extras

These features listed will enable you to know what to keep in mind as you make your choice of manometer. Kindly continue reading to further glean the implications these factors can have on a manometer.

Recording pressure readings in the comfort of your home or office is totally achievable as long as you have the right manometer and are conversant with its usage. Generally, manometers are simple to operate. There are different kinds of manometers:

• The U-Tube Manometer - This is the most common type of manometer made of a glass tube bent in a U-shape. It is partially filled with liquid with a higher specific gravity as compared to the test liquid’s own pressure. It has both its arms open to the atmosphere and is also used to measure suction pressure. As pressure is applied to one side of the tube, the liquid recedes in that arm and the level goes up in the other; this continues until the fluid weight and attendant pressure balance up. The U-tube manometer can also come as the differential kind or inverted form; the former is used for miscible liquids and the latter for light liquid as compared with the test fluid.
• A Micro Manometer - This one features arm that has an increased surface area. It is used to measure high precision with minimal variations in pressure.
• Inclined-Tube Manometer - Just as the name suggests, this particular one features an inclined tube, in which infused fluid can move a longer distance. It has a high sensitivity and accurately measures low pressures.

A good number of manometers can retain readings, with a ‘freeze’ screen function that enables you to save readings in the device memory. This is a great feature since a log of the pressure calculations you have done for a time period can be easily accessed. When the manometer memory is full, some of the data can be wiped off to make room for a fresh set of readings.

Most modern monometers come with cases, made of durable plastic in which they are carried. The case encloses the main parts of the manometer, preventing them from damage, water and the effects of harsh weather.

Indicator fluids are stabilizing liquids used in liquid manometers to measure the pressure of the liquid under consideration. Water and mercury are the most commonly used ones. Water is a light liquid and is suitable for measuring small and sometimes seemingly insignificant differences in pressure. Mercury on the other hand and other ‘heavier’ indicator fluids are more useful for calculating large variations in pressure. The heavier the indicator fluid is, the higher the range of pressure that the manometer can measure. Other indicator fluids like benzene, colored water and bromides also exist. Before deciding on an indicator fluid to use, you have to consider the prevalent temperature, flash point, vapor pressure and density among other things.

Manometers could be digital or analog. The analog type is one of the oldest forms of manometers. They are usually crafted from sturdy, durable, and pliable polyvinyl chloride (PVC). They offer precise measurement of the pressure of gases and liquids. With an analog device, some calculations are bound to be made after readings have already been taken, which can be tedious. So here comes the more modern variation: the digital manometer!

Like a breath of fresh air, this device is refined and is a handheld device that is great for calculating differences in pressure and other interrelated factors. It is more specific, has a high reading accuracy and is convenient to handle. It is an incredible tool to have in the house and is useful for checking the propane level of your home appliances like barbecue ovens and indoor grills. They can also be used to detect faults in heat ventilating and air conditioning systems. Digital manometers can be hooked up to your computer. They are portable and suitable for field work, can be mounted on a base or put up on a panel.

Some manometers are available with batteries included, while for some others, you would need to buy them yourself. As soon as you purchase your device, it is advised that you fix in new batteries or replace the ones that the manometer was delivered with. Digital manometers require fresh batteries, as these are important for good calibration and precise readings. Most manometers have a battery-saving mechanism that causes them to go off if left unused for about 20 minutes. Re-illuminating the LED backlight display is just by a push of the power button.
