Kintrex IRT0421 Holiday Deals Review

Most people don't seem to realize that the accuracy of this thermometer (all infrared temperature sensors) is very dependent on a property of every material called "emissivity". In general, you will get a more accurate reading when the material has a high emissivity. Materials with low emissivity will reflect infrared light. If the material has a *very* low emissivity, such as with aluminum foil, then the device will be reading the temperature of the objects that are in the foil's reflection - such as the kitchen, the oven interior surface, and even yourself. Luckily, most of the surfaces associated with foods being cooked have a high emissivity (water, flesh, oil, plant matter, etc), so the device will be fairly accurate with those. But there's another thing to consider for cooking applications - this device still is only measuring the surface temperature. With foods like meats, you are still going to want to use a temperature probe so that you can measure the inside temperature.
This device should work well with measuring temperature of candy, melted soap, oils, foods cooked at relatively low temperature such as breads, or food that you are re-heating. It should also work very well for examining doughs.
It should also work well on most non-metallic painted surfaces.
It should work *somewhat* on windows, as they have a fairly high emissivity, and low transmittance to infrared (that is, infrared light does not pass through them even though visible light does).
Do *not* use it on any unpainted metals. After reading specifications and reviews of similar products in the same general price range. I decided on the Kintrex IRT0421.

I am very pleased with my purchase. This device is very quick to respond and it seems to be quite accurate when used properly. One of the main reasons I chose this infrared thermometer over the Fluke, Raytek or Sears Craftsman was that it uses 2 AAA batteries rather than a 9-volt battery. I've had the Kintrex for about a month now and I'm still using the original batteries which show no signs of weakness yet. The display is very easy to read even in a dark room (it's backlighted) and you can switch from Fahrenheit to Celsius simply by pressing a button.

As far as I'm concerned, you can't beat the Kintrex for the price. This is a great product and definitely lives up to its product description. The unit has a solid feel and I don't have the impression that it is a low quality product. Temperature readings are quick and accurate as far as I can tell. It provides many uses such as confirming the temperature of foods to finding heat sources in your home. It has helped me pinpoint the areas in my house that I am losing precious air-conditioning.

My biggest problem with the thermometer is the laser, the infrared temperature reads from a much larger area than the laser points to and until you get used to the unit you may be confused by the temperature reading for areas at a distance of 4 feet or more away.
