The thermal scope is the reliable device that can quickly and accurately scan the temperature of the object’s entire surface, and visualize the received data. You can find a great number of thermal scopes at the market, just look at Thermal Sight for Sale and you can be a disoriented. However, what one will be suitable for you? So, let’s find out.
How to choose the thermal scope: 10 helpful pieces of advice
1. Buy the thermal scope with the highest resolution of a matrix.
The temperature range fixed by the device, the amount of error in the results, the temperature sensitivity threshold depends on the matrix size. Nevertheless, the thermal scope may be small, but very powerful.
2. Look at the frame updated rate.
If the thermal image is updated with a frequency of 50-60 Hz, it can allow watching the movement of object in real time. But, if it is less than the object can somewhat slow down and be indistinct in sight.
3. The sensitivity of the thermal scope must also be taken into account.
It is the minimum value of temperature, different from the own noise of the detector, which device is capable to recognize. Such parameter is called as NETD (Noise equivalent temperature difference). The best devices have a value of NETD about 14-15 mК, the averages – 50-80 mК. Practically this parameter means what size of the target and at what distance you will see it.
4. Choose the thermal scopes based on the range of temperature measurement.
Temperature range shows the lowest and the highest temperatures with which the thermal scope can work. It is worth choosing the device with a large temperatures range. It gives you the opportunity to explore objects in different conditions.
5. It is worth paying attention to operational characteristics.
This set of parameters shows in what conditions of the environment the device will correctly work. Therefore, at the choice, it makes sense to choose devices that will work well in the conditions of high humidity, and just as in frost winter, and in the summer heat.
6. Another important indicator, which should be taken into account angular field of vision.
It is the largest size of an object located in the field of device vision, measured in degrees. If the view angle is smaller, then you will continue to move away from an object the better, without losing a sight. Also, choose the optical system, which can be rotated by 120 degrees. It allows reaching even the remote objects.
7. The ergonomic position is very significant.
The weight is rather important, especially if you constantly use the device and hold it suspended. Lightweight thermal scopes allow reducing the load on hands and shoulders. A size of device is very significant too.
8. Pay attention to the protection of thermal scope.
The higher is it, the better. Such devices are executed in shockproof, sealed, water- and dustproof cases, successfully withstand the sudden temperature differences and mechanical influences that are equivalent to the falls on hard surfaces.
9. The availability of functional capabilities can be a great addition to the thermal scope.
The better devices are equipped with multiple functions. There is a lot of distinctive features of them, but everything depends on the purpose of your buying.
10. Look for the most profitable conditions of warranty service.
The most proven manufacturers are confident in their products and are willing to give the best long terms warranty. Some of them offer the expanded warranties for buyers.
Certainly, the thermal scope is a serious and a quite expensive device. Making such a purchase, you must clear understand of when, where and how it will be used. And, based on this knowledge, choose the most suitable model.
