Here, we have a sturdy, useful dual-port manometer designed for HVAC/R field professionals. Besides measuring static pressure, this digital device works with differential and gas pressure.

The device’s design allows users to operate it with just one hand. On the front, the manometer has a convenient set of buttons to control each one of its functions, including zero adjustments, data hold, and one for on/off.

Additionally, the manometer includes a magnet at the rear for the better hanging of the device while operating. While active, you can use it to measure pressure from 60inWC to 60inWC and from 150.0 to 150.0mBar.

Another useful feature of this device is that it can measure the pressure of two points to calculate the difference between point A and point B.

Included in this purchase, customers also receive a compact adapter as an extra accessory. Upon testing it, the adapter did well while measuring inlet and outlet gas pressures.

One big missed opportunity for the makers of this product is the backlit feature on the manometer’s screen, which doesn’t come included. If you’re using the device in workspaces with low visibility, chances are you’ll have trouble reading the measurements.

So, don’t let it catch you by surprise, and take a flashlight with the rest of your tools!

5. Dwyer Mark II Liquid Filled Wall Mount Manometer

This product is probably not what you’d expect while searching for modern manometers. Still, after testing it, we can corroborate that the Mark II can easily be the best liquid manometer out there.

First, the interface is simple and easy to understand. This manometer has a wall mount design, featuring a styrene-acrylonitrile housing for improved durability. The scales, the ABS zero adjustment knob, the indicating tube, and the fluid wells also deliver outstanding resistance for regular use.

Plus, due to the uniquely expanded 0 to 3 scale, taking readings is much easier.

After setting it up at the designated place, the manometer measures above and below atmospheric pressure while also offering the option to take differential pressure readings.

Another feature worth mentioning is the zero lever included, which provides linear recalibration.

Despite being a wall mount device, this manometer can turn into a portable tool with the addition of the A-612 stand and tubing. Sadly, this benefit isn’t easy to access, as the purchase doesn’t include the stand. For that, you’d have to buy it separately.


  • Super affordable price makes the unit accessible for hobbyists that need a capable manometer
  • Provides accurate measurements
  • Durable housing with plenty of resistant materials
  • Expanded scale allows users to take readings easily


  • Customers must purchase the stand separately

Buying Guide: What to Consider When Choosing Manometer


Even if we consider we’ve found the best closed-end manometer, there’s a set of features we should consider to know whether or not that manometer would meet our demands. These elements don’t only apply to closed-end manometers but to all of them too.

a) Build and Design

First and foremost, we must understand that manometers are available in different sizes, shapes, and they also work differently.

As seen during our manometer review article, we covered a variety of models like the u-tube manometers, water manometers, and the open end manometer, to name a few.

Before picking your ideal manometer, make sure its type is the most suitable for your activities.

b) Features

Whether you’re looking for a simple manometer or just the best manometer, there are a set of features your ideal pick must provide. Most prominently, you have to focus on the type of manometer, the indicator liquid, the power source, and memory, among other aspects.

c) Analog or Digital

The analog manometer has been around for decades. Often made with sturdy polyvinyl chloride (PVC), this type of manometer offers precise pressure measurement while testing gases and liquids. Still, you have to do a lot of calculations afterward, which isn’t fun.

That’s when the digital manometers come into play. These can calculate differences in the pressure automatically, among other tasks. When compared to analog, digital devices are far more efficient.

d) Hold Function

An underrated function of manometers in the data hold function, which freezes the screen to save readings in the memory of the device. Though not every manometer offers this option, digital handheld devices must have it.

Regardless of your purpose, having this function could help your efficiency significantly.

e) Accessories

One useful accessory that you may want to consider purchasing is a protective case to keep your manometer perfectly stored.

Frequently Asked Questions

1. What can you measure with a manometer?

You can use the manometer to measure absolute pressure in inches of water columns. Alternatively, this tool can determine the force gas or liquid exerts on another fluid, thanks to gravity.

2. How to read a manometer?

It depends on the type of manometer. If you’re working with a digital tool, then reading it is as simple as looking at the values on the screen.

Other manometers may require you to figure the difference between the left and right tubes’ heights, which you can later use to calculate the pressure. In these cases, you’d have to put in a lot more effort, patience, and you may even need a manometer diagram to fully understand how it works.

3. Which one to buy between analog and digital manometers?

Though it depends on the preferences of each individual, digital manometers are the superior choice for a lot of people. They’re convenient, easier to use, and require less work on your part.

4. Are manometers accurate to measure pressure?

Yes, the manometer is a reliable tool that efficiently allows you to measure pressure.

5. Manometer mercury vs. water, what’s the difference?

As opposed to water, mercury does not evaporate. Plus, since it has a lower freezing point, Mercury won’t freeze at 0 C. Reasons to consider mercury over water manometers are due to their visibility and stability.

Final Words

Found your best manometer yet? As long as you keep in mind the information discussed here, you should be ready to go and get one of these tools for pressure measurement. Remember to consider the type, the features offered, and the accuracy of the manometer.

If you do, then you’ll narrow down the list from ten to a single product that efficiently meets your expectations.
