Is suitable for the rapid detection of the car scene, can be equipped with a laptop computer;

Light source: the use of cluster pulse power supply;

Optical system: a short focal length lens focusing, a colorless, and a full sealed to avoid light dimming system;

Injection system: automatic built-in batch pump system;

An atomic device: a low temperature automatic light argon hydrogen flame, a shielded quartz;

Automatic sampler with 80 or 160 bits;

Power on self test, automatic control, automatic protection, automatic alarm system;

Gas liquid separation device with chemical vapor phase, automatic water vapor device;

With hydride generation atomic fluorescence detection of harmful elements in the tail gas trapping device, effectively prevent the environmental pollution caused by the two;

Standard 232/485 - RS communication, powerful in English and Chinese language software operating system, can realize automatic system diagnosis, automatic sample measurement, standard curve measurement, a variety of reporting formats, and save the expert help system.

Unique upgrade module:

With the form analysis part and related operating system, the form of As, Hg, Se, Sb and other elements can be carried out;

With special gas mercury detection device, the determination of Trace Mercury in air can be realized;

Ultra trace mercury detection device with special water, sea water, surface water detection of ultra trace mercury (detection limit = 0.0002 g/L);

With direct sampling and testing of cadmium, cadmium can be directly detected in solid and liquid samples without sample pretreatment;

With direct injection of mercury, the mercury in solid and liquid samples can be detected directly without sample pretreatment;

Direct detection of mercury and cadmium in the same measurement device can directly detect the mercury and cadmium in solid and liquid samples without sample pretreatment.
