## Questions & Answers

**Q: I measured the temp of steel leaving a furnace at 2250f and the bt-1800 read the temperature as 152f at 1 ft away - if closer, unit would melt?**
A: Both lasers have to be superimposed on each other to get the correct reading.  I have to be at least 2-3 feet away to get the lasers to be on top of each other.  If both lasers are not on top of each other your reading will probably be way off.  When both lasers are on top of each other pull the trigger and the temp should show up.  I don't use it for exact measurements.  I use it to tell me if I'm getting close, or if I am way high.  Metals melt at specific temperatures so it is easy to use this meter to keep you informed as your temperature builds in the forge.  Any I don't have to get super close to get a temperature which keeps me from melting the unit or my hand.

**Q: can i return this product as does not seem to be very accurate with temp readings?**
A: Google the laser reflectivity chart and that might help.

**Q: what does AH mean on the display ?**
A: Hi AH means out of measuring range, or service temp. Please try stand further from the heat during the test

**Q: can this be used on people to measure tempeture?**
A: Thanks for asking! It's great question! 
This high temp pyrometer is designed for measuring surface temp of nonliving object. Measuring people temp would be off.
