Hello.
ST490+ is a non-contact infrared thermometer.
It can measure temperatures from -58℉ to 914℉ and can be set in the emissivity range of 0.1 to 1.00.
In addition, the laser point in the measurement range is output, supporting high / low temperature alarm output.
The first half of the content is unboxing and the second half includes tests for temperature measurement.
I hope it helps viewers to purchase their products.
