<html> Jack,    Got pages and pages of temps from info gathered for a class. Wait till you get your new toy on stage, man. It's cool. You can check your temps on struts and strings and actually out-guess the pitch drop! If you have a regular venue or two (or ten), you can get some averages for how much change to expect under the lights and with an audience, etc. It's funny how different it can be for different groups, like symphony or choir. Once you get a fair idea of the swings, you're looking at about .8 cent per degree F. The fun comes when you run out during intermission, etc., with an ETD and the IR thermo to check stats. Way cool. Mine is a Radio Shack 50 buck model. I lust after the one I saw at the radiator shop that had a laser pointer built in, and would read from 2 feet away. Have fun! Oh, and don't forget to take it outside with you next time you BBQ. Tells you alot about how your smoker/grill/ whatever is working.

An infrared thermometer lens collects and focuses the infrared energy onto a sensor.The sensor produces a small voltage output, proportional to the target temperature, which is processed and displayed. You can just aim and push the button and read the current surface temperatures in less than a second. Here is a sample reading of a grand piano I just tuned.    Kawai rx2 is in a dining room, the back of the piano is 2ft from a window.   Outside temperature is:    45*f Inside window:                 56*f Outside wall:                   62*f Back of piano:                 63*f Bass bridge:                   64*f Front,near keys:              68*f   The instrument gives the customers and myself  a good idea of varying degrees of temperatures around the piano. I have yet to use it on a piano with bright lights shining on it.   Jack</blockquote></html>
