Atomic Absorption Spectrophotometer

Special FeaturesInside and outside aerosol -like the path of
rays integration structure and the CAN-BUS analysis system, guaranteed instrument's extendibility.

Can install 10 hollow cathode lamps (possible to install two high performance
hollow cathode lamp)

The patent light signal processing system and high accuracy circuit design,ower electric noise, high antijamming ability

Thermostable, anticorrosive entire titanium burner head, inertia polyphenylene
sulfide atomizing chamber, had guaranteed easy to clean and the non-memory
effect.

Intellectualized work software, realizes breakdown self-checking, as well as automatic
background adjustment function.

Comprehensive security countermeasure, instrument exceptionally protects, acetylene
revelation warning, the undervoltage protection etc.
