仪器简介: Use this economical flame photometer for routine determinations of sodium and potassium in industrial and educational applications. This easy-to-maintain unit gives you fast and accurate results. An automatic gas shutoff mechanism activates if the flame becomes accidentally extinguished, ensuring your safety. Unit comes with one each of Na+ and K+ filters, two meters each of gas and air tubing, and necessary fittings. Order optional lithium, calcium, and barium filters separately. Note: Filters are factory fitted, please specify at time of ordering.
