The Laser Thermometer by Doug Fincher

September 26, 2016 - We got a Harbor Freight coupon last week that offered their laser thermometer for half price.  I have for over forty years blued firearms and found that controlling the temperature of the bluing solution was the diciest part of the job.  Hand-holding a thermometer within inches of boiling caustic (sodium nitrate and sodium hydroxide boiling at 290 degrees)) can cause serious burns….and  having  a thermometer that would let me to take a reading from several feet away seemed too good to be true.
