This mode displays the oral-equivalent value of the measured forehead temperature. This unit measures the temperature at the surface of the forehead by sensing infrared emission of the skin at the measured point, and then calculates the oral-equivalent value using a unique algorithm based on actual body temperature survey data.
Surface measurement mode shows the actual and unadjusted surface temperature of an object, which is different from the body temperature. This mode can help you determine if the object temperature is suitable for a patient or baby (such as baby milk).
It is a very accurate device. Used it on the same day when I received it. The product comes in a very nice packaging. I liked the quick delivery of the product by Droozo. Would recommend to family and friends
