What is a RoadWatch and how does it work?

Posted on

RoadWatch is a device that is able to measure the temperature of a surface by measuring the heat that is radiated by any object warmer than −459.67°Fahrenheit (referred to as absolute zero). This means everything that we encounter in the real world is radiating heat. The easiest way of thinking about this is to look at a standard incandescent light bulb that is turned on. We can see the light from the light bulb as well as feel the heat being radiated from it when we hold our hand near the bulb. The heat that we feel is known as...

How much salt for the temperature? Knowing the temperature of the road can be extremely important, especially when trying to clear the ice and snow filled roads with salt to make safer driving conditions. The temperature of the air and the road differ, this is because there might be wind, or not much sunlight on the surface. The road could be starting to freeze when the air temperature reads close to 36F, which is why having a RoadWatch to know the exact road temperature becomes so important for safety. When putting down salt on the road, it is important to...

How accurate is RoadWatch?

Posted on

RoadWatch was initially designed to measure the road surface temperature most accurately (± 2°F / ± 1°C) when the ambient air temperature is between 23°F and 41°F (-5°C to +5°C). Unlike other manufacturers, the RoadWatch Bullet is fully calibrated from 15°F to 105°F for twelve air and road temperatures with ISO-9000 process controls and using a NIST traceable reference. Every sensor must pass a post-calibration verification to complete the manufacturing process. See the image above for a screenshot of a real-time production/calibration. The test shows the air temperature, ranging from 14 F to 38 F, and how each air channel...
