BTMETERBT-1800 Non Contact Pyrometer High Temperature Infrared Thermometer Gun -58CF 3272CF (-50 1800 ) DS 50:1 for Metal Melting Furnace Forge Kiln Tempe Tester (Not Accurate for Human Temp)

Good

I liked the style and price...Sadly it was broken upon arrival so i couldn't use it as i'd hoped to.

I just unboxed the 1800 and went around testing it. My hand came back at 108ºF. My daughter across the room came back at 106ºF. The inside of my freezer came back at 41ºF (which is above freezing ... in case people don't know that) ... I went outside where it has been cloudy and 45ºF all day today. My cat's water bowl came back at 85ºF ... not likely. I am in the process of a return for this. But I am putting it out there that the accuracy is very suspect. I would have understood +/- 2º ... but this is crazy.The instructions were not super clear either. There is a mode button on the interface. I could not figure out what "mode" was to do. There is an F and C button which went back and forth between the measurement types. So then what does Mode do? I could not tell you because the instructions don't say. Pretty difficult to get excited about a product when it does not work well, and the instructions don't explain how to resolve issues very well either.I would not recommend the 1800 model.

Works as advertised.

The directions are not complete, there is no instructions telling the user that after 999 degrees Fahrenheit the display indicates only 3 digits, not four. In other words a reading of 112 is actually 1120 degrees. It took us several hours to figure that out and a useless, expensive call to China.Also, in the review questions you ask about accuracy, like everyone has a way to confirm accuracy.The user manual is poorly written. I do think the instrument could be a good buy if it is truly accurate and a fourth digit would be added to the read out.Updated Review November 25, 2019BTMeter has been working diligently to make corrections regarding the issues mentioned in my original review. Once I learned how the meter reads, I too have found it a very useful tool. It is being used to measure the internal temperature of gas forges in the range of 1000 to 2600 degrees Fahrenheit. Switching from Fahrenheit to centigrade is as easy as punching a button.Though I still have no way to report accuracy the numbers generated are useful.At this time I would revise my review to a four star and once the manual is updated and the screen readout gives a direct four digit reading, I would then rate the instrument with a five star.

Found out reading a review that the thermometer can only display 3 digits. So when temperature is >= 1000 it moves a decimal left and displays 100 for 1000, 110 for 1100 degrees, etc.... Would have expected this to be clearly called out in manual; I didn't see it anywhere in the manual.
