Product Description

Digital Flame Photometer

 Digital Flame Photometer - 381 is considered as a simple & easy to operate instrument for the determination of Sodium, calcium, Potassium and Lithium. It is considered as an perfect and ideal instrument for the purpose of soil testing labs. These Digital Flame Photometer is a two sided channel flame photometer which has been widely used for the purpose of simultaneous observation of Sodium and Potassium levels in the blood serum (plasma), Urine and other kinds of biological fluids.
The instruments are mainly supplied in 2 units which are Main Unit and Compressor Unit. The Main Unit is made up of digital displays, detector, filters and nebulizer. The compressor unit then supplies the dense or compacted air to the main unit. Air at a given pressure is then passed on into the atomiser. The suction which when produced by it, will draw the sample solution into the nebulizer and then it is further sprayed as a fine mist back into the flame. The light which is emitted by the component at the distinctive wavelength is then secluded or cut - off by the narrow band interference filters, which then descend on to the silicon photodiode. Post the signal conditioning of the photodiode output, it is then being sent to the digital converter and the outcomes are then displayed directly in the ppm / meq units. The narrow band obstruction filters are then mounted on a rotating disc which has been fitted within the Main Unit. A suitable and apt filter can be chosen by rotating this disc with the help of a thumb. In addition to all this, this oil free compressor comes with a regulator which can help sustain a stable airflow.
