I want to buy an IR thermometer that can measure the temp of individual header pipes and the radiator. This one http://shop.advanceautoparts.com/we...rmometer-Pro-Sunpro_9090013-P_N3412_T|GRP2083____ goes up to 932 degrees F. Seems pretty high but is it enough to measure the headers? Or, any recommendations for another thermometer? Thanks.
Don't need that much. I got mine from NAPA for around $35 and it does just fine. Now, if you are measuring header pipes after or during a high speed run (I would love to see you try DURING a run!!!) it may get that high or higher, but at idle, where I bet you will be using it, it will be plenty. Mine ranged from 210 to 450 degrees (that is how I found my walked-off rocker).
http://www.google.com/products/cata...og_result&ct=result&resnum=3&ved=0CDgQ8wIwAg# Here is the one I use. Used mostly for taunting the cat, but also for measuring temps in my jet-boat engine, cooking oil temps, a/c and heater ducts, header tubes, cooking surfaces on pans and barbecue grills, etc. You will find no end to the uses of these things.
I'm surprised that 750 degrees F is hot enough for header tubes. Looks like a good one and less money than the one I was looking at. I'll order it. Thanks!!
Like I said, if it is just idling, and you want to find a cylinder that is cooler than the others due to something sticking or broken, then it should be fine. If, on the other hand, you want to compare them after a balzout run, it may not be hot enough. A high revving engine may get hotter than the 900 degrees you are able to measure with it (or the 750 I am able to measure with mine). But i see no reason why you would even WANT to measure temps on headers at that time. Keep in mind, water boils at 212, so a 250 and relatively "cool" header tube will still scorch skin and oil and water will burn off of it quickly. But it is by no means "hot" at that temp.
check Harbor Frieght, Beware,,, family and friends will want to probe you where the sun dont shine after you temp everything near!!!
Used mine (Raytech or something like that) to measure my header tubes before and after Jet-Hot coating (dropped 200 degrees). The color of the surface you're measuring will affect the accurracy, black is most accurrate. If you're comparing 2 or more temps it's not a big deal.
I have a Raytek, I keep it in the kitchen. Awesome when I grill some steaks! I never tried it on my headers....Wow the light bulbs above me are 235 Degrees!!
