Temperature measuring gun cannot be measured below 10 degrees.

There is a minimum value below the set value. Temperature measuring gun cannot be measured below 10 degree, because it is lower than the set minimum value. Temperature measuring gun has a certain temperature measuring range, and the temperature outside the set temperature range will affect the operation of the machine. If the surface temperature of the human body is lower than the minimum range of the thermometer in cold weather, the human body temperature will not be measured and the display screen will not display. Therefore, temperature measuring gun can only be accurately measured in a warm environment.
