IRT0401 Compact Waterproof (IP67) Infrared Thermometer

I purchased this product for measuring the engine temps of nitro RC cars. when tuning an RC car - the head temp is an important way to determine if you're running it lean or rich.this IR thermometer is perfect for doing this.. its small, and accurate (when used next to a much larger/more expensive laser unit - it measures withing a few tenths of a degree each time) and the readings are pretty fast.I haven't tested out its waterproof abilities yet, but it feels solid, and has o rings in all the appropriate spots - so i don't doubt them.One neat feature which i'm not sure was documented - if you press and hold the button, you get continuous readings... useful for scanning over a larger area to look for hot spots, or just to ensure a more accurate picture of whats going on with whatever you're measuring.the only thing i wish it had was a backlight - but i'm not deducting a star from it, because it never claimed to have one.All told - i'm very satisfied with this purchase, and have already recommended it to friends in the RC hobby. The price was great, and the performance is a lot better than i expected for the price.

I purchased this device mainly for the interest at finding out various temperatures around me and the readings all seemed to be accurate. It's a very small device that gives out fast readings, so it is nice to be able to take this on-the-go easily.Unfortunately, being this small it is also prone to accidentally being left in a pocket and going through the wash. It said it was water proof, which I hoped that it was, however after finding it after it had been washed I am stuck with an "Er 3" on the screen and erratic readouts.I'm sure a brief submission into water wouldn't hurt it, but "waterproof" does not mean "can go through the wash."With that said I will be purchasing another as really it was only my own fault that it went through the wash.

Seems like a pretty accurate sensor (measured oven and freezer temperatures along with other thermometer). Not bad for $20. It is as easy as pushing a button and the result shows up pretty fast. So far, it seems quite durable (I have not tested its waterproofness yet but plan to take it canoeing). It is nice to be able to push a button on the underside to change between Celsius and Fahrenheit.Sometimes, I wish it lit up in the dark or had a built in laser, but no matter, I knew I wouldn't be getting that.EDIT 3-24-12:Not as waterproof as I'd like. I tried measuring water temp by submersion but that only made the thermometer give strange readings. Everything went back to normal once it had time to dry.I cannot get accurate high temperature readings (namely, my ski waxing iron). Ski waxes need between 110 and 150 degrees C to melt (each wax has a specific melting temperature; they smoke if the iron is too hot). My iron melted the waxes and made them smoke, but the temperature readings on the iron's surface only read between 50 and 65 C. At least temperature between ice water and body temperature are still accurate.

This was the first infrared thermometer that I've ever bought. It works great. Its wonderful to have a device that allows me to see how cold the "cold spots" in my house are to see if they are a problem. It is also nice to double check my oven and make sure that it is getting as hot as it should be. My husband and I love it. I'm really glad that it shuts itself off after 10 seconds or so. We have a bad tendency to forget to shut off our digital thermometer... so its great that this one turns itself off after a few seconds and keeps the batteries lasting longer.My only "complaint" is that its a little difficult to push the button to turn it on and off. Sometimes the button seems to get stuck too, but its nothing major in my opinion considering the price. Other than that, its a great bargain!EDIT: 11/10/11I down graded it from 4 to 2 stars. The product isn't as great as it was when I first bought it. It first was fine, but a month or two afterwards... not so much. It drains the batteries quickly, the screen flickers and sometimes won't even come on. The cap when replacing the batteries doesn't want to stay on. It still does technically work, so its not getting a 1 star. I retract my previous happy 4-star statement and want to warn you that its really a 2-star. Perhaps mine was flawed, maybe mine had problems and it was a fluke... I don't know. Perhaps I expected more for $20. I ended up getting a slightly more expensive trigger-thermometer. I trust more in my new trigger-thermometer's accuracy. This one still seems accurate, that is - if you can read the flickering screen.Buy a different product for the long haul - it'll save you money and grief.
