Why Distance-To-Spot Ratio is an important factor when buying an IR thermometer.
The accuracy of any IR thermometer is determined by the distance-to-spot ratio. This ratio is the size of the object that you are measuring in comparison to the distance from where you are taking the measurement. In other words, the further you are away from the object the larger is the area being measured. If you are measuring a specific spot on a piece of equipment you may need to be quite close to achieve an accurate measurement, depending on the IR thermometer used.
An example of how to use spot ratio follows. If you are measuring a target area of approximately 125mm diameter wide (e.g imagine the area of a man's clenched fist), and your IR thermometer has a spot ratio of 8:1, then the maximum distance you can accurately measure temperature is maximum 1.0 metres (i.e.: 8 x 125mm = 1000mm - see illustration below). Beyond this distance the thermometer will also be measuring the temperature of the area outside the 125mm target diameter, which will obviously deliver a less accurate reading.
The biggest factor when shopping for an IR thermometer should be distance-to-spot ratio. In this case a higher ratio is better than a lower ratio as it will allow you to take accurate, targeted measurements from a greater distance.
