Flame photometer equipment offers the advantages of compact size, user-friendly operation, and stable reliability. The entire series comes standard with ion detection flame failure protection devices, ensuring safety and dependability. It finds extensive application in industries such as agricultural fertilizers, soil, cement, and ceramics, as well as in the analysis and determination of silicate industries and pathological research in medical and health fields. The flame photometer utilizes liquefied petroleum gas as its fuel.
Features direct concentration readout for five elements: K, Na, Li, Ca, and Ba, capable of simultaneously displaying up to three elements in any combination.
Equipped with an RS232 interface for connecting to printers and PC software.
Includes automatic correlation coefficient calculation, preset flame size selection, standard curve storage, and single-point calibration functions.
Equipped with flame failure protection and a moisture separator.
Features menu-driven keyboard operation.
