Part 3/7:
Inside the kiln, the glowing alumina caught Ryan's attention. He hypothesized that the instrument used to measure temperature—the Williamson—was possibly yielding low emissivity readings. He compared this against the published emissivity values necessary for their work with the Optris. It was expected that higher emissivity values were required to align the readings accurately but suspected that infrared energy from inside the material contributed to the inconsistent readings.
Measurement Techniques and Adjustments
As they proceeded, Ryan conducted a series of measurements using the Williamson device, revealing that it recorded varying readings as he moved the probe nearer to the material, suggesting an increase in infrared energy detected.
