WGH6441 Flame Photometer, K/Na/Li/Ba Measurement (CAT#: STEM-BC-4151-ZJF)

The WGH6441 is a multi-element flame photometer for potassium, sodium, lithium, and barium. It applies emission spectroscopy to quantify elements excited by flame energy. The instrument can present up to three selected element concentrations simultaneously. Its barium measurement range extends to 3000 µg/mL. The LCD and menu-based keyboard provide clear access to analytical functions. Correlation coefficients are calculated automatically during calibration. Standard curves can be stored, and single-point correction supports routine verification. Preset flame adjustment and flame-out protection improve operating consistency and safety. RS232 communication and a moisture separator support computer connection, printing, and stable gas flow.
