 "Not a Fluke, but still a worthy meter" 2009-07-12
By Benedict J. Jackson (Portland, OR USA)
I selected this meter based on the variety of measurements (including the IR thermometer, which I had used before in a lab) and the price. I find it is a very capable meter. I like the builtin stand, the backlight, the sharp probes and the large display.



The one area where it really falls short (and even led me to believe it was broken the first time I encountered a 470 in a lab) is the auto ranging. It is much, MUCH slower than a Fluke, and while it is auto ranging it displays the random outputs at the wrong ranges. That's the main thing that keeps me from giving it 5 stars. One other slight weakness is the audible continuity tester. My Fluke 10 has some minimum beep time which you can hear even if you barely brush something. The Extech's beep is on for exactly as long as the probes are connected. If you brush against something you might only hear a strangled click or screech.

 "Mis-represented" 2009-01-10
By D. Nimer
The "Title" of this item indicates it comes with 2 K Type thermocouple probes. In the manufacturers description it infers the probes range is to 1832 F. "The truth is it comes with 1 type K probe only usable to 482 F". The other mis-representation is that it comes with a protective Holster. The truth is it comes with an orange protective rubber over cover.

I would like to see these inaccuracies corrected on the Amazon web site but cannot see a way to contact them.
