WGH6450 Flame Photometer, Five-Element K/Na/Li/Ca/Ba Analysis (CAT#: STEM-BC-4152-ZJF)

The WGH6450 is a five-element flame photometer for potassium, sodium, lithium, calcium, and barium. It uses characteristic emission produced by flame-excited atoms to determine concentration. The instrument supports quantitative analysis over the individual ranges listed for each element. Up to three elements in any selected combination can be displayed simultaneously. A menu-driven keyboard and LCD simplify method configuration and result viewing. Automatic correlation calculation assists with calibration evaluation. Standard curves can be saved, and single-point correction is available for routine adjustments. Preset flame control, flame-out protection, and a moisture separator support reliable combustion conditions. The RS232 interface allows connection to PC software and compatible printers for result management.
