Product Description

Product Description

The IRT0421 Non-Contact Infrared Thermometer with Laser is designed to accurately measure temperature from a distance. Simply pull the trigger and aim the pistol grip thermometer at an object using the laser indicator and the unit will provide an accurate temperature measurement in less than a second. The IRT0421 has an advanced highly accurate infrared sensor with a Distance to Spot Ratio of 12 to 1. It uses two AAA batteries instead of the 9-volt battery commonly found in less capable units. With its low voltage application-specific integrated circuit, battery life is increased by up to 60%.

This infrared thermometer provides accurate readings over a broad range of temperatures, from -76 to 932 degrees Fahrenheit (-60 to 500 degrees Celsius).

Easy to use and very accurate.
Trap Shooter
Works as advertised, more than accurate enough for our use (frying, checking the oven, & checking car engine temp).
rigs
Temperature readings are quick and accurate as far as I can tell.

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.

I bought it because of the low price & was surprised to find it works just as well as more expensive Fluke thermometers I've used in the past. It works quickly, has a good distance to spot ratio and it's priced just right. I've used it for everything from spot temp checks of computer equipment to checking my freezer & my ceiling insulation coverage. I would buy the same one again if it were lost or broken.

Simple to use, no set up required.

Product does NOT have adjustable emissitivity which means it can read higher or lower than the real surface temperature depending on the reflective consistency of the surface being measured.

This product is fine for a quick ball park temperature reading and is great to use to scan across a surface to find any temperature deviation like a wall area.

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.

But all in all a great product.

I'm an Electronics tech thus I tend to sometimes over-research everything bufore buying... that said (and based on all the good reviews here on Amazon) I decided on this Kintrex. When it arrived I thought the box may have been empty since it had no weight, but it wasn't. After opening I tried to put bats. in but the chinsy plastic compartment wouldn't close. It has 3 very tiny (1/16") plastic tabs to hold closed & they were bent. I can't see it lasting beyond the first battery change before they break, by then it would be out of warranty. I used elastics to keep it closed so I could at least test it out. Measurements I took under 150 deg. F. were between 10-20 deg. off. I waited a couple of hours, tried again, still off. There are SOOO many things I didn't like about it, I just don't have the time to list them all. After testing it for a few days I returned it to Amazon (they are GREAT about this stuff) & got the Raytek instead. When it arrived the box felt like there was a real "tool" inside... hmm, so far so good. I put it through it's paces, indoors & out, day & night. I'm now a happy camper! The Kintrex was like a cheap Chinese toy compared to the Raytek. For only about $10. more the Raytek is the tool to get, without a doubt. Very accurate & consistent. It may not be as durable as a unit costing $150. bucks or more, but it's measurement's & ease of use would compare to anything out there. It's so much better designed. I even tested it out in the mirror with the lazer pointing under my tounge & much to my surprise it was only slightly off measuring between 98-99 deg. (the Kintrex measured between 70-80 degrees under tounge) Obviously these are not designed for that purpose but the Raytek measured darn close to my medical infrared thermometer!Read more ›
