Color change. When the steel reaches a straw yellow color it is at the right temperature to quench and temper.

The color test depends on the type of steel used.
Testing if a magnet will stick to the steel is another method that works for 1095 but may not work with lower carbon steels like 1060 or stainless steels.
The Crucible in Oakland has a thermometer like what you are talking about. Call them and ask for Chris, he runs the blacksmith shop.

Temp Sticks work very well; I used them while restoring an iron bridge some time ago. The temp sticks are calibrated to different temperatures. When you swipe the material, the stick will melt if it's up to the temperature, and it will leave a chalky line if it's under the temperature.
Aside from that, color is your best bet, even if you're colorblind like I am. Don't waste your money on high-end pyrometers; better to trust your instincts. The time and material you waste earning will be more than compensated by your learned expertise and experience.
