WGH6432 Flame Photometer, K/Na/Ba Measurement (CAT#: STEM-BC-4149-ZJF)

The WGH6432 is a flame photometer configured for potassium, sodium, and barium measurement. It uses flame emission intensity to determine elemental concentration in prepared liquid samples. The instrument covers a barium range extending to 3000 µg/mL. Up to three selected elements can be presented simultaneously on the LCD. Menu-style controls simplify method selection and calibration. Automatic correlation calculation supports evaluation of standard curves. Users can save calibration curves and apply single-point correction when required. Flame size can be preset, and flame-out protection improves operational safety. RS232 output and a moisture separator support external data handling and stable gas delivery.
