You can use the incandescent lamps to calibrate your camera. You vary the temperature of the filament by a variac. You can measure the temperature of the filament by a pyrometer. You can measure also the temperature of the filament by camera.

Hello Aditi,

The type of calibration depends on the type of camera. For "two-color" pyrometers, radiation at two wavelengths are collected and processed to determine temperature and are inherently more reliable that the "single color" variants. If a manual for the camera is not available or does not indicate the method of calibration, I would ask the manufacturer. If that is not an option, and I had a facility to monitor temperature-time plots for an alloy or two using the device and check the changes in slope and also the solidus and liquidus temperatures.

Kind regards,

Hello Aditi,

You can verify the temperature by using pure silver but you should be make sure that silver is pure or not. Therefore, you can want a certificate of the silver (about silver's information) from the manufacturer.

After that (being sure that silver is pure), pure silver's melting point is 961,8 °C.

When your temperature is 961,8 °C, your silver should melting.
