The WGH6430 is a multi-element flame photometer for potassium, sodium, and lithium measurement. It uses flame heat to excite sample atoms and detects the resulting element-specific emission. Concentration values are calculated from the measured spectral intensity. The instrument can display up to three selected elements simultaneously. An LCD and menu-style keyboard provide straightforward operation. Automatic correlation calculation assists with standard-curve evaluation. Flame intensity can be preset, and standard curves can be saved for future measurements. Single-point correction supports routine analytical adjustment. Flame-out protection, moisture separation, and RS232 communication improve safety, stability, and data handling.
