Concept Alloys was formed in 2002 by former technical staff of Hoskins Manufacturing Company. The company manufactures its' products in their facility located in Whitmore Lake, Michigan, USA. It specializes in the production of tungsten-rhenium alloys for temperature measurement using proprietary manufacturing and testing/calibration methods.
Tungsten-rhenium alloy combinations can be used over a wide temperature range that extends from –196°C to over
2,760°C. Standard temperature tables (ASTM E230 and E1751) are available from 0°C to 2315°C. These alloy combinations
are susceptible to rapid oxidation at high temperatures and are not recommended for use in oxidizing environments.
They are very stable at high temperatures in reducing or inert atmospheres such as hydrogen, inert gases and vacuum. The cost of these materials is relatively low ompared to noble metals.

Great and effective ending to a quite beginning. thanks for sharing the video.

I believe it peaked out at 65 millivolts. Use charts to calculate temp based on thermocoupler used.

I assume you are showing temperature measurement difference in Celsius between the samples?
I cannot read the display clearly.
Can you dictate what it is displaying when you have time?
Thanks,
