## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ You can spend more money if you want to but .....
*by C***C on August 31, 2023*

I have an independent geology lab (ie gold prospecting) and continually melt ore samples to determine any degree of value in precious metals. The tasks must be as expedient an accurate as possible. You can't melt quartz and feldspar without knowing how hot the samples are getting. This device will measure up to 3,000F, which is sufficient when looking for gold and silver. If you are looking for platinum groups, you will need a device that measures temperatures above 3,000F.When using it, always make sure you extrapolate "distance" from the source and add about 50 degrees for every inch or so to what you are reading.There are other devices that are more expensive but, this device, for the price, this is the best value.

### ⭐⭐⭐⭐⭐ Pyrometer
*by T***M on November 13, 2023*

Menu like on most of these instruments is not intuitive. But enough playing around finally got all the setting right. Seems to be accurate in the forging range

### ⭐⭐⭐⭐ Accurate at high temps, easy to use, hard to read screen in sunlight
*by A***R on November 3, 2024*

Bought it for use with my homemade forge to get the melting temps I needed without excess wear on the crucible. Works great on finding hot spots in fire pits as well.Con: in the daytime, even shaded screen is hard to read
