For a non-contact thermometer that goes from -50 to +500 degrees such that price and royal. To those who cry for 3 degrees delta between measurement and reality, I put their consulting 100 more. This is a thermometer that can target very quickly differences 5 degrees of temperature for the insulation of a house, to see the temperature of the oven .... This is not a medical purpose or precision. I am delighted with this purchase, I use it regularly. Important note: the 9V battery is included
