Over the past decade, I’ve looked at over 200 of the best Wi-Fi routers and while giving each a hard workout, I checked their temperature with my trusty Fluke 62 Mini Infrared Thermometer. Its red laser pointer allowed me to nose around the router looking for thermal hotspots. Inefficient sure, but I got pretty good at it.
Lately, I’ve found a better way to take a router’s temperature. I now use Topdon’s TC004 thermal imaging camera that delivers a thermal image instead of random temperature readings. The 3.5-inch display shows temperature as color with a scale on the right.
