Factors to Consider When Buying a Digital Monometer
Before you go to the market, always consider what you will use your manometer for. This will help determine the ideal one that will serve your needs. Outlined below are other important factors you will need to consider before finally buying a digital manometer though.
Construction and Design
Most digital manometers are constructed in almost a similar ergonomic design. They have a dual port on the top, a magnet at the rear, an LCD display on the front with the zero buttons slightly below the display.
They are usually small and light in weight and this design makes them easily portable.
However, it is good to note that some features differ in terms of size. The size of the LCD display varies from one digital manometer to another. Some have a widescreen, which is advantageous because you will not have to worry about straining to read the digits that appear. Some are small but equally enough.
Features of An Ideal Manometer
Digital manometers have many features in common. They are handy and portable devices usually of small sizes and very light in weight. In fact, their weight can be measured in ounces. This makes them very easy to carry around.
Common features of any digital manometer are; a display (mostly LCD) that shows the results, the 11-scale unit that measures weight in different forms, a magnet that helps to hang the meter and a zero adjust button that resets your device.
Almost all digital manometers use the 9-Voltage lithium battery. All the 5 manometers listed in this guideline use the 9V Lithium battery.
To be specific, the lithium battery is fitted with all the devices bar one manometer (Perfect Prime AR1890 Professional Digital Air Pressure Manometer) which requires you to purchase the battery separately.
Performance refers to the accuracy and the number of tasks a manometer can execute. Different manometers have different accuracy levels and different tasks that they do when measuring pressure.
Most digital manometers have an accuracy ranging from ±0.01inWC or 0.01mBar to ±0.003mBar (highest to lowest). These statistics, however, show that most of the digital manometers are accurate while the most accurate ones stand at ±0.01inWC
In terms of tasks, most digital manometers are generally used in the most common area of application, which includes: in HVAC, pneumatic controls, gas appliances, medical purposes, laboratory testing, gas appliances installation and repair.
The best digital manometers have a high performance. They will let you do your measuring job without having to worry about accuracy and the tasks they are capable of doing.
User ability refers to the ease of use of a manometer. User-ability usually depends on the features that accompany the manometer. The features that are incorporated in the digital manometers make them easy to use.
Almost all digital manometers have an LCD display that helps you to read your measurement clearly. The lightweight design of manometers makes it easy for you to carry, hence, easily portable. The 11-scale unit measures weight in different forms. The magnet helps to hang the meter and a zero-adjust button assists in resetting your device back to zero.
However, there is a slight difference among the manometers in terms of size of display, weight and even the size of the manometers in general. Manometers with a relatively larger display are easy to use. They will let you read your results on the display without straining your eyes.
Different kinds of digital manometers are available at the market at different price tags. The price range is brought about by the differences in quality, functionality and incorporated features. The features differ in accordance with the functions they execute.
Quality always comes at a price. This is to say that, you are going to dig deep into your pockets if you want to buy a high-quality digital manometer. A quality manometer has a high performance, is highly accurate, and comes along with unique features that make it easy to use.
Most digital manometers recently developed are of high quality though. The five picks are the highest rated in the industry but differ in prices due to functionality and additional features they come with.
At the end of the day, all you have to get is an affordable manometer that will meet your demands without having to dig so deep in your pockets.
The measurement of pressure is as old as time. The manometer, simple and precise, is one of the oldest ways to measure the pressure of gases and fluids. Getting the right gas or liquid pressure measurement is basically dependent on the kind manometer you will use.
Hence, you need to choose a digital manometer with high accuracy and excellent LCD display. These types of manometers, will not only give you accurate pressure readings but will also offer a nice display that is easy to read the results.
The most important thing to consider when buying a digital manometer is its performance and ease of use. The construction and design plus features and the accessories that come along with them do not largely differ.
That said, you should get a digital manometer that meets your demands, has a considerable warranty and is affordable.
