When measuring light-emitting surface temperature, such as aluminum and stainless steel, the surface reflection will affect the infrared thermometer readings. Before reading the temperature, you can put a strip on metal surface. When the temperature balanced, measured regional temperature of strip.
      If you want to make sure that the infrared thermometer can still provide accurate temperature measurement from kitchen to cold storage area back and forth, it is necessary to measure again after over a period of time in the new environment to balance the temperature. You’d better place the thermometer in commonly used places.
      Use the infrared thermometer to read internal temperature of liquid foods, like soup or sauce, must be stirred before metering surface temperature. In order to avoid pollution lens and prevent incorrect readings, thermometer should keep away from steam.
