Surface t measurements
The range of surface temperatures that the instrument can effectively measure.
In general, the meaning of this parameter is quite obvious. We only note that an extensive operating range is not always an advantage. First, it affects the cost of the device; secondly, when the range is extended, the measurement accuracy may deteriorate. So when choosing, you should not chase the maximum temperature range, but take into account real needs: for example, it hardly makes sense to choose a pyrometer with an upper limit of 500 °C for measuring the quality of thermal insulation and determining heat leaks in residential premises. It is conditionally possible to divide pyrometers into those that are for measuring low temperatures, and, accordingly, for high ones.

Power source
- "6LR61". A standard 9-volt Krona battery is rectangular in shape, with a pair of contacts at one end. Quite a popular option: for a number of reasons, 9 V voltage is very convenient for use in pyrometers.
—AA. A popular standard size of replaceable cells is known as “pen-cell batteries”. Similar elements are also available in the form of rechargeable batteries. In pyrometers, such power supply is less common than “Kronas” - in particular, because several AA batteries are usually required for effective operation. However, this is also a fairly popular option.
- AAA. Another common standard size of replaceable elements is “pinky batteries”. Similar to the AA described above in everything, with the exception of a smaller size and, accordingly, lower capacity. They are used mainly in compact devices, for which even AA batteries are too bulky.
— Branded battery. Powered by its own battery of the original standard, which can also be made non-removable. On the one hand, such power has a number of advantages over replaceable batteries. Thus, the battery is initially included in the kit, it does not need to be purchased separately; and when the charge is exhausted, there is no need to spend money on fresh batteries - just leave the device to charge. On the other hand, charging requi...res a power source and takes quite a long time, while batteries, if there are spare ones, can be changed in a matter of seconds. Therefore, this option was not particularly widespread.
- CR2032. Quite miniature “tablet” batteries with a diameter of 32 mm and a thickness of 2 mm. Due to their low capacity, they are used extremely rarely - exclusively in miniature devices designed for maximum compactness and, as a rule, intended for short distances (up to 1 m).
There are also models with combined power supply that can operate from one or another source.
— “Krona” / external power supply. Models capable of operating both from the Krona battery described above and from the supplied AC power supply. The advantage of this option is that if there is an outlet, the device can be connected to it, saving battery power (or even charging it if a battery in the “Krona” form factor is used for power).
— AA / branded battery. Devices that can operate both from replaceable AA batteries and from a branded battery. To do this, the package usually includes an adapter that allows you to install a set of batteries instead of the battery. Note that the battery itself is not necessarily supplied with the pyrometer - on the contrary, batteries may be included in the package, but the battery must be purchased separately (or removed from another instrument of the same brand - some manufacturers use universal interchangeable batteries for their devices). See above for more details on each type of power supply, and their combination gives the user a choice and, in theory, allows them to mutually compensate for deficiencies. On the other hand, in most cases it is easier to buy replacement elements in the form of batteries than to mess with a branded battery, so this option is not particularly widespread.

Max. operating time
The maximum operating time of the pyrometer on one battery or accumulator charge (see "Power").
In general, the meaning of this parameter is quite obvious, it is worth noting only one nuance: different brands of replaceable batteries can vary significantly in capacity. Therefore, when using inexpensive elements, the actual operating time of the pyrometer may be significantly less than the claimed one.
