Measuring temperature in shiny surfaces:
It has been found that in the case of shiny surfaces, temperature measurement by infrared thermometers is affected by the reflectivity of the surface. Shiny surfaces here may range from aluminum and steel to non-stick cook wares. So, for gauging temperature in these kinds of situations, it is very necessary that you provide coating in these surfaces. This may consist of non-stick cooking spray, or masking tape that covers the reflective metal surface.
Measurements in extreme environment:
It is always important to keep the infrared thermometers in a place where it is being used frequently. This is because change from one extreme temperature to another can affect the functioning of these instruments to a great extent. For example if you have to gauge the temperature of an object that has been moved from the kitchen to the above freezing point or cold storage area, you can get accurate reading provided time is given to the infrared thermometers for acclimatization.
Use lightweight, compact, and user friendly infrared thermometers and measure temperature of objects even when they are hot, hazardous or are inaccessible to reach. And yes, use the above mentioned tips and you can never go wrong in temperature measurement of any object.
