Pros & Cons of - FLIR C5 Thermal Camera

Verdict for FLIR C5

The resolution of the FLIR C5 is an excellent tool for your inspections.

It’s an essential preventive maintenance tool that allows you to troubleshoot your equipment in a fraction of the time.

From detecting water leaks in your HVAC to electrical hot spots in your equipment, there’s not a single professional who wouldn’t benefit from using the C5.

We love the large temperature range and the ability to adjust various parameters of the C5.

However, we are not the biggest fan of the WiFi connectivity and Ignite features. Absurd as it sounds, you cannot transfer images directly from the C5 to your phone or computer.

You have to upload images to FLIR Ignite Cloud, then download them to your device. It’s a hassle for many who are looking to quickly complete the image upload.

However, for most professionals looking for a reliable pocket-sized thermal camera, you’re looking at the right page.

FAQs about Thermal Cameras

Q1. How does a Thermal Camera work?

Most objects give off infrared energy, known as a heat signature. 

A Thermal Camera detects and measures infrared energy.

It converts the data into an electronic image, which displays the measured surface temperature of the object or objects. 

Your data that you’ve collected can give manufacturers instant feedback on the area or equipment that needs immediate attention.

This helps you and your facility to improve your overall preventive maintenance efforts – guaranteed to reduce the risk of an emergency breakdown

Q2. How accurate is a Thermal Camera?

It depends on the quality of the Thermal Camera, and the type of surface or object being measured.

Thermal Cameras with adjustable emissivity (which can greatly affect measurement accuracy) are more accurate.

Some Thermal Cameras allow you to adjust other parameters as well as ambient temperature, reflected temperature and atmospheric pressure to achieve more precision effectively.

Thermal Cameras with lower thermal sensitivity or Noise-Equivalent Temperature Difference (NETD) will also be more accurate. 

It measures the smallest temperature difference that a Thermal Camera can detect in the presence of an electronic circuit or water seepage.

Thermal sensitivity is measured in milliKelvins (mK). 

For example, cameras with 50 mK are about 4 times as sensitive as a camera with 200 mK. 

The more sensitive (50 mK) cameras provide a wider temperature difference, resulting in more colours on the thermal display.

Q3. Should I rent or buy a Thermal Camera?

We understand that high-end Thermal Cameras can be pricey.

This is because the cost of a Thermal Camera varies according to the capabilities it provides in return. 

In this case, renting a Thermal Camera for one-time use may sound like a fantastic idea.

Because you’re allowed to experiment with various Thermal Camera brands. 

You will be able to gain more Infrared experience in using Thermal Cameras if you decide to rent these cameras. 

However, once you buy a Thermal Camera, you’ll always have the tool nearby – saving you the trouble of scheduling meetings and renting it.

In this case, our best advice would be to consult an Infrared Thermography Expert to understand how various Thermal Cameras work and how to effectively operate them. 

This is to avoid wasting your money on purchasing the wrong equipment for your intended application.

This way, you’re 100% certain that you are investing in the right tools.

Ready To Become The Hero Of Your Facility?

If your job involves industrial facility maintenance, firefighting or HVAC, you’re familiar with the application of Thermal Cameras. 

Nevertheless, even if you’re just a homeowner who prefers to fix wiring, plumbing, ventilation, and similar issues of your own, you would need one of these life-changing technologies.

And that is because EVERYTHING that light touches emit thermal energy. 

With the abundance of choices in the market, it’s not an easy task to choose your ideal Thermal Camera…

“Here’s the Secret: What matters most are 2 things – what you plan to shoot with it, and how much you have to spend.”

Thermal Cameras have been a valuable tool in helping us to identify thermal or electrical issues both quickly and efficiently. 

 A picture is truly worth a thousand words.

 On this note, we hope that our list of Top 10 Best Thermal Cameras has inspired you in selecting the best model for your needs. 

 If you’re still wondering how to fully utilize and unlock the potential in your Thermal Cameras, seek professional advice from Infrared Thermography Experts to ensure you are investing in the best tools for your maintenance application.
