How to choose a thermal imager?

In order not to make a mistake in choosing a thermal imager, you should carefully study such parameters as:

device type - portable devices and devices for a smartphone are available for sale.
If autonomy and durability are the main thing, it is better to choose the first option.
When instant reporting is required, a smartphone instrument is ideal;
temperature Range - pay attention to the minimum and maximum temperatures.
At the same time, it is important to take into account the temperature of the working areas with which you will have to interact, and based on this, make a choice;
accuracy of results - a key indicator in determining the quality and functionality of the measuring device.
Experts advise purchasing equipment with an error of 1.5-2% - this is the best indicator;
software – models designed for connection to a smartphone have free software, which makes it possible to carry out a full-fledged analysis.
If the camera supports Wi-Fi, the user will be able to create reports both on the smartphone and on the device itself;
detector resolution Infrared cameras have a lower resolution than conventional cameras.
High resolution will allow you to get high quality images, which means that the research results will be as accurate as possible;
the presence of a laser pointer - the pointer can help if the object cannot be called safe.
On digital photos of the visible spectrum, laser markers are clearly visible, which is one of the main advantages of this feature.
