AA-7050D Atomic Absorption Spectrophotometer

The AA-7050D employs a double-beam total reflection optical system, automatically performing zero return, scanning, lamp positioning, mirror adjustment, and energy balancing based on the element wavelength selected in the method. It is widely applicable in metallurgy, petrochemicals, geology, medicine, environmental protection, scientific research, agriculture (soil/fertilizer), disease control, food safety, materials science, and commodity inspection. Capable of analyzing over 70 elements, it plays a critical role in micro and trace elemental analysis.
