I've got an Extech - bought from Northern Tool, but it's been discontinued. Guess it was TOO affordable ... :roll:

Haven't been on there to see what has replaced it .... but this is a pretty good brand. It's been in coal ash, it's been wet, and it's been dropped. Hasn't missed a beat in 4 years yet.

Rick this a no name brand called "HT-822 IR thermometer" got it on amazon.com for 13 bucks even came with a 9 volt battery, so 9 or 10 bucks minus the battery! Works great, I check it every month or so on a given known temp-boiling water or glass of ice water.

I have the same one from Amazon, works well at room temperature, when pointed at anything approximately room temperature on up to the sides of my stove, 300 to 800 degrees. Also gave me good readings on the engine block of my car which corresponded closely to the coolant temperature sensor. When I took it into my cold cellar (about 35 degrees) it measured the interior walls at 17 degrees which can't be right. Then I chilled it in my freezer and measured walls on a cold porch that I knew to be about 40*, and the readings changed a lot as the thermometer itself warmed up. I think you're supposed to give it a long time to stabilize to ambient temperature, so probably the bad readings were my own fault. But for the ways I normally use it (to measure warm stuff rather than cold stuff) it works very well.

Buy a Fluke off of Amazon or Ebay...

The IR's have there place but aren't really that accurate for many applications. Try measuring a copper suction line off of a refrigeration unit, or inside of a walk-in cooler.

I only use Fluke 62 IR to check temps coming out of heating/cooling ductwork in high ceilings. Otherwise I use my Fluke 51 II which uses a K thermocouple. It's very accurate. I picked this one up off of Ebay for $50. Everyone wants the Fluke 52, 53 models so these sell at a high price on Ebay. I am a refrigeration tech so I use my 51 everyday usually for box, superheat & subcooling measurements.

Thanks for the replies.

Just got the spring HVAC shop tools catalog and it's about time I get one of these gadgets for the shop.

CAP, I see that they now have a Fluke Model 62 max or 62 max plus. They claim that these are good even if dropped from almost a 10 foot drop. Sounds like just what I need. I wonder if it will take getting thrown 30 feet across the shop floor on a hot Friday aftertnoon ???
