Usage and Conclusion

Using the thermometer is extremely easy; much like a digital camera, just point-and-shoot. As mentioned earlier, the closer you are to your target, the more accurate your readings will be. The specifications list accuracy of 2C/3F. This should be plenty accurate for our general purpose measurements.

I tested the infrared thermometer on various items around my apartment which was actually pretty entertaining.

From top left to bottom right, MOSFETs in my test system (very hot!), CoolIT beverage chiller surface, LCD monitor surface, laptop exhaust area, hot water in the sink and freshly cooked Pizza Bagel Bites. Notice that when the trigger is held down, the LCD screen is backlit blue. This lasts for about 8-9 seconds after you release the trigger and lock in the temperature.

As you can see, the possibilities are limitless with the infrared thermometer. I knew that MOSFET chips got warm but I didn't think they were "that" hot! I actually tested a lot more things then posted here, such as the surface of an oven burner on high (600+ F before the thermometer reached its upper limit and ERR'd out), toilet water temperature (72.6F) and even proved my theory about my mini fridge to be true (canned drinks at the bottom of the fridge are 10F cooler than those stored on the upper shelf).


The Non-Contact Handheld Infrared Thermometer is a nifty little gadget to add to your computer (and household) toolbox. This thermometer can be used to measure numerous "hot spots" in your computer, such as the Northbridge/Southbridge heatsinks, CPU heatsink, RAM, video card core (or the backside of the card, or various chips on the card), hard drive surfaces, MOSFET chips, etc. There are a ton of possibilities here and you might actually discover something is hotter than you would have guessed!

This is one of the few "multi-purpose" products we have reviewed here. Take the thermometer with you while you are working under the hood of your car, check the vents of your heater / air conditioner, measure temperatures of pipes around your home, etc.

I have actually been looking to pick up one of these wireless thermometers for a few years now, but the price tag has always kept me from making the purchase (most I have seen retail around $100.00). Granted, this is a "lower end" model that lacks some of the features of higher-end models (thermocouple wire monitor, greater temperature range, better distance to spot ratio), most of these features aren't really needed for everyday use. As of writing, the Non-Contact Handheld Infrared Thermometer sells for only $29.99 over at
