FP-640D Dual-Channel Flame Photometer for Sodium and Potassium

The FP-640D Flame Photometer is a laboratory analytical instrument designed for quantitative measurement of potassium (K) and sodium (Na) using flame emission photometry. It uses a photocell receiver, interference-filter spectral system, and dual-channel digital display for simultaneous or convenient monitoring of both elements. The instrument is suitable for clinical chemistry, pharmaceutical, agricultural, food, environmental and research laboratories where routine sodium and potassium determination is required. Key Features Dual-channel digital display Measures Potassium (K) and Sodium (Na) Photocell receiving system Interference-filter spectral system Flame emission measurement principle Stable and repeatable analytical performance Coefficient of variation of ≤2% Simple benchtop operation Suitable for routine elemental analysis Useful for clinical, agricultural and chemical laboratory applications Specification Details Product Type Flame Photometer Model / Art.
