Digital Flame Photometer

Digital Flame Photometer is a simple & easy to operate instrument for

determination of Sodium, Potassium, Calcium & Lithium. It is an ideal instrument for soil testing labs.

The instruments are supplied in two units viz. Main Unit and Compressor Unit. The Main Unit

comprises of digital displays, detector, filters and nebulizer. The compressor unit supplies the

compressed air to the main unit. Air at a given pressure is passed into the atomiser. The suction

produced by it, draws the sample solution into the nebulizer and is sprayed as fine mist into the

flame. The light emitted by the element at the characteristic wavelength is isolated by the narrow

band interference filters, which then falls on to the silicon photodiode. After signal conditioning of the

photodiode output, it is sent to digital converter and the results are displayed directly in ppm/meq

units. The narrow band interference filters are mounted on a rotating disc fitted within the Main Unit.

Appropriate filter can be selected by rotating this disc with the thumb. The oil free compressor with

regulator maintains a stable airflow.
