A Buyer’s Guide

Once you’ve decided to buy thermal leak detection equipment, you need to determine which is the right product for you. The problem is that there are so many different options out there that it can be almost impossible to decide quickly and easily.

If you’re wondering what you should be looking for in a thermal leak detection kit, we look at some of the factors that you need to bear in mind here so you can avoid making an expensive mistake.

  • Price

Your budget will, in the end, determine which product you can afford to buy. The good news is that there are some excellent products which can perform well but which can be bought for a relatively low price. While you usually get what you pay for, and therefore it’s often a bad idea to go with a bargain basement model, if you opt for one of the mid-range products that offer plenty of features but at a reasonable price you can get the best of both worlds. Bear in mind that a little more money spent initially can pay off in the long term with a more durable and long-lasting product.

  • Application

Another key element to consider is the applications for which you intend to use your gadget. Are you only using it at home to work out where you’re losing energy and therefore where you could benefit from a little more insulation to save money on your bills? Or are you a professional contractor who needs to use the device for work related tasks? If so, your needs will be much more demanding than those of the average DIYer. You’ll need to make sure that your chosen device is highly durable and resilient as well as very accurate. You’ll also need to make sure that you have an LED light for use in less than optimal conditions and you could also benefit from the facility to transmit and store information in real time.

  • Additional Features

Many thermal leak detection kits offer a host of extra features which you may or may not need. If you’re a DIY user with very basic requirements, it isn’t always worth your while to pay extra for an all-singing all-dancing device which can do a whole range of things that you’re never going to need. You need to identify the key features that you’re going to need in your chosen device before you buy. For example – are you going to require a moisture pen to identify water leaks? Do you need the humidity levels to be recorded? There are many extras which may be included and you need to work out whether any or all of them are suitable for you.

  • Reporting

If you’re only buying a thermal leak detection kit for your own use at home, you’re certainly not going to be using any reporting features, however if you’re a contractor who will be out on site, being able to transmit information and data in real-time back to the office could be highly beneficial or even vital. Having inclusive software to enable you to create and send reports is also probably going to be an extremely useful feature if you’re buying a kit for professional use, and the extra outlay for one of these more advanced devices will be well worth it in the long run.

  • User-Friendliness

If you’ve never used a thermal leak detector before, you could probably benefit from choosing an intuitive device with user-friendly controls. You don’t want to have a steep learning curve to get to grips with before you use your gadget for the first time. Make sure that you’re choosing a model which is easily navigable and which has been designed for ease of use. While you’re considering user-friendliness, pay attention to the screen size of the device. A larger screen will give you much greater visibility when it comes to getting all the details.

  • Accuracy

Perhaps one of the most important elements to bear in mind when you’re choosing the right thermal leak detector for you is the accuracy of the gadget. If you only need the device for home use, you may not require such precise accuracy as you would if you were using your device for professional applications, however you still need to be sure that you’re getting the right results. If you’re a professional contractor, accuracy is absolutely paramount, especially if the results that you are getting will result in your breaking open a roof or wall. Accuracy in these cases means being able to detect even a small anomaly and state of the art imaging software will allow you to get the best possible results.

  • Sensitivity

How well can your chosen detector detect infra-red energy? While one device may only be sensitive to temperature chances of 0.10 degrees C, others have sensitivity to temperature changes that is as much as 0.05 degrees C. If sharpness of image is key to your application, you’ll need to choose the most sensitive detector you can find.

  • Temperature

Another element to keep in your mind before you make your final choice is the temperatures which you’re going to need to measure. How high or how low a variation in temperatures are you going to have to visualize? Some models are capable of measuring temperatures as high as 662 degrees F – ideal for use by professionals, while others are only capable of measuring much lower temperatures. The type of application you need your device for will determine the specifications that you’re looking for in your chosen gadget.

  • Warranty

Whichever device you end up choosing, you should make certain that you are benefiting from a manufacturer’s warranty on your purchase. Without a warranty, you won’t be protected from any potential faults or defects. At a bare minimum you should look for a manufacturer’s warranty of at least one year and preferably two if you want to be certain of the best possible protection and coverage against any potential problems.

If you follow these buying guide tips, you should find it easier than you imagined to make the right choice of product for you. Whether you’re a professional or a home user, you’ll find that if you bear these points in mind you’re sure to select the perfect thermal leak detector kit to suit your individual requirements.
