Review on Myron PT2 Temperature Pen - The Ultimate UltraPen for Precise Temperature Measurements by Draven Invert

I purchased this unit after using the Myron L Ultrameter II for a year with amazing accuracy. This pen is way behind their other product. First, unlike an ultrameter, it had to be calibrated right out of the box. Even after that, I got different readings for the same sample, differing by up to 2 points, not 0.2 seconds. This paragraph takes a long time to witness. at least 30 seconds. At nearly $200 this thing should be perfect.
