Bellstone Digital Flame Photometer Model BHI-LSR-439 is a simple & easy to operate instrument for determination of sodium & Potassium Calcium & Lithium are optional filters. It is an ideal instrument for soil testing labs.
Digital Clinical Flame Photometer Model BHI-LSR-442 is a Dual channel Flame Photometer used for simultaneous observation of Na & K in blood serum (Plasma), Urine & other type of biological fluids.
The instrument are supplied in two units viz. Main unit and compressor unit. The main unit comprises of digital display, 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 solution of the sample into the nebulizer and is sprayed as fine mist into the flame. The light emitted by the element at the characteristic wave length is isolated by the narrow band interference filters, which then falls on to the silicon photodiode. After signal conditioning of teh photodiode to the silicon photodiode. After signal conditioning of teh photodiode output it is sent to analog to digital converter and the results are displayed directly in ppm/mEq value 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 on a rotating disc fitted within the main unit. Appropriate filter can be selected by rotating this disc with thumb. The oil free compressor with regulator maintains a stable airflow.
