The Atmosphere Hawk

Do you measure the density of air in your experiments?

 

Some aerodynamicists assume that the density of the air they are using is 1.2 kg/m3 or 1.225 kg/m3.

 

But it almost never is either of these values. The temperature, barometric pressure, and humidity change every day, every hour, and even every minute. That causes changes in the density of air. Typically, the density of air fluctuates 2-4% every day. (See the graph below.)

 

That 2-4% creates errors in everything:

 

The Reynolds number will be 5-10% different.

The Strouhal number will be 5% different.

The velocity of the air in your wind tunnel will be 2-4% different.

 

Validating your CFD becomes difficult and erroneous because in your CFD, you've assumed one air density, but it's not the same as in your validation experiments.

 

All of these errors waste money and time because you have to do more experiments and spend longer validating just to find something that works...if you can find something that works.

 

That's where the Atmosphere Hawk comes in.

 

 

 

The Atmosphere Hawk accurately gives you the density of air in your experiments based on its accurate measurements of the temperature, barometric pressure, and humidity.

 

It prints it on a large screen so you can see all of these values any where you are in your lab. It also connects directly into your computer.

 

Researchers who have used this device have seen savings in the order of $10,000s and even $100,000 through saved time and resources. They have also seen dramatic increases in their research output because now their data is more valuable.

 

The Atmosphere Hawk is very robust. See this video where we destroy it with a hammer...at least we try to.

 

It is also very easy to use. All you do is plug it into the power and it works.

 

Below is the accuracy of the Atmosphere Hawk.

 

If you want to make your research better and save yourself a lot of time and headaches, get the Atmosphere Hawk for your lab.

EASY-TO-USE

Our aerodynamics instruments are the easiest to use. They are also very robust. We routinely try to smash them with a hammer...for fun. Here is a video showing us do that.
