Pyrometers with LED light

Backlight

— the presence in the device of its own backlight. In this case, both conventional and ultraviolet illumination can be implied. The first actually complements the pyrometer with a flashlight function and makes it easier to work in low light conditions. UV illumination, on the other hand, is primarily designed to detect refrigerant leaks in air conditioners and refrigeration units: many refrigerants contain an additive that glows in UV rays. The specific type of backlight for each model should be specified separately.
