WGH6410 Flame Photometer, Dual K/Na Measurement (CAT#: STEM-BC-4145-ZJF)

The WGH6410 is a flame photometer for quantitative analysis of potassium and sodium in liquid samples. It uses flame emission spectroscopy to excite atoms and measure their emitted spectral intensity. The measured signal is related to the concentration of the selected element within the specified range. An LCD presents concentration results and operating information directly. Menu-based controls support routine instrument setup and measurement. The system automatically calculates correlation coefficients during calibration. Flame intensity can be preset before analysis, and flame-out protection improves operating safety. Standard curves can be stored for later use, while single-point correction supports routine adjustment. An RS232 interface enables connection to a computer or printer, and an integrated moisture separator conditions the gas path.
