Factors affecting emissivity

October 15, 2017By Bob BerryGeneral

What factors affect the emissivity of an object? Material Non-metals, usually have a high emissivity, and are usually fairly constant over time. Metals on the other hand can have a very low emissivity, and as they usually oxidise, their emissivity tends to vary drastically over time. Surface Polished and shiny surfaces tend to have lower … Read More

Why thermocouple readings don’t compare with camera results

October 8, 2017By Bob BerryGeneral

Why thermocouple readings don’t compare with camera results   Question received by email, slightly edited; We are busy working with a foundry that mainly does High chrome white irons. The problem that we are encountering is that there seems to be a variance of about 80°C between our thermal camera and the thermocouple that they … Read More

Can infrared thermography measure gas temperatures?

April 10, 2017By Bob BerryGeneral

  All gases have different properties. Some gases certainly do emit infrared energy. However, they normally only emit in a very narrow spectral band. Thus seeing a gas is certainly possibly by using a camera adapted with a suitable spectral filter. Seeing the gases is not the same as measuring its temperature, and there are additional … Read More

Why does an infrared remote control not affect thermographic measurement, while the reflection of a person can?

April 3, 2017By Bob BerryGeneral

Why does an infrared remote control not affect thermographic measurements, while the reflection of a person can? This is a question of wavelength. Infrared remote controls operate in the near infrared range (e.g. 0.85 µm or 1.55 µm), while thermographic cameras usually work within MWIR (3-5) µm, or LWIR (8-14) µm. The remote controls simply do not emit … Read More
