Default IR Thermometer for $8

If you live close to a Harbor Freight store, you can pick up an IR Thermometer for $7.99 from now until 4/13/09 (Edit: new coupon is good to 5/11/09). Just print and present the coupon in this ad

You can use this thermometer for checking the temperature of your laser diode and its driver, or building a laser power meter (Simple Laser Power Meter Using IR Thermometer)

When this sale is over, you can still buy it from their web site.

Also, they sometimes go on sale in the local stores for $9.99, or $7.99 with a coupon. You can sign up to receive ads and coupons by mail, or check the weekly Extra Savings Coupons.

Default Re: IR Thermometer for $8

Hey, i'm notin the US so i couldn't buy this thermometer.

Could you buy it for me, and send it with the cheapest shipping costs?
I'll pay you thermometer+shipping+a fee for bothering to buy it for me

How about $12?

Default Re: IR Thermometer for $8

Those little thermometers are great! I use one all the time to temp nitro & gas engines as well as electric motors and LiPos in RC boats.

That is a fantastic price, even without the coupon. Last season I purchased one from Tower Hobbies that was much more expensive. *

Also worth noting are the helping hands for only a $1.89. Good for holding your laser steady or clamping down the button on pen-style pointers that require the button to be held down. Magnifying glass too.

Thanks for the link to that coupon list. Between the thermometer and the helping hands, I'm gonna have to go to the one 20 minutes away and pick them up.

I picked one of these up. Unless water boils at 181F, this thing is off by a bit. Although it seems to be +/- 2 if it's not reading a liquid or a metal ???

Doesn't water boil at 212 F? They are very nice meters, and for 8 bucks you can't beat it.

Maybe what you're getting is the temperature of the steam mixed with air? What happens if you tack a piece of black adhesive tape onto a pot with boiling water and take the temp of that?
