Harbor Frieght Infrared Thermometer

This weekend, I bought a Harbor Freight Non-contact Laser Thermometer.  I'll explain why in a later post, but I gotta say, I'm impressed with how well this thing performs... especially since it costs $39.99... and I had a 20% off coupon!  :)

First, the laser doesn't "do" anything--  its actually just a pointer to help aim the thing.  Its really a focused infrared measurement device.  The instructions state that it has an accurate range of about 8 feet.  After that, the accuracy begins to drop, but from my minimal experimentation, the loss of accuracy is negligible.  Truthfully, if its accurate within +/- five degrees, it will be worth the price.

The device uses one nine volt battery, which gets depleted fairly quickly. 

Note:  The instructions do not explain how to install the battery.  The front part of the hand grip (black part) slides down.  At the top of the grip, near the trigger, there are four ridges on each side.  Hold the top of the "gun" in your left hand, squeeze the ridges with the thumb and forefinger of your right hand, and slide the grip away from the top of the gun.

 Here's some backyard fun.  With fire!

 Sure beats licking the coals to see if they are hot enough.
