How Infrared Thermometers Work

Infrared thermometers, like the Milwaukee 2278-20, operate by detecting the infrared energy emitted by objects and converting it into a temperature reading. The device’s lens focuses the infrared radiation onto a detector, which then translates the energy into an electrical signal. This signal is processed and displayed as a temperature reading on the device. The 12:1 distance-to-spot ratio of the Milwaukee 2278-20 ensures precise readings from a distance, enhancing user safety and convenience.

Understanding Infrared Thermometers

Infrared thermometers, like the Milwaukee 2278-20, operate by detecting the infrared energy emitted by objects and converting it into a temperature reading. The device’s lens focuses the infrared radiation onto a detector, which then translates the energy into an electrical signal. This signal is processed and displayed as a temperature reading on the device. The 12:1 distance-to-spot ratio of the Milwaukee 2278-20 ensures precise readings from a distance, enhancing user safety and convenience.

Understanding Distance to Spot Ratio (D:S)

The distance to spot ratio (D:S) is a crucial specification for infrared thermometers. It indicates the diameter of the area measured by the thermometer at a specific distance. For instance, a 12:1 D:S ratio means that at 12 inches away, the thermometer measures a circle with a 1-inch diameter. The Milwaukee 2278-20’s 12:1 D:S ratio ensures accurate temperature readings from a safe distance, making it suitable for various applications.

Accuracy and Performance

In testing, the 2278-20 demonstrated excellent accuracy across various surface materials and temperature ranges. Readings were within 1-2°C when compared to a calibrated thermocouple.
