Features
Fast analysis
High precision
Good stability
Low detection limit
Many analysis elements
Easy to operate, new Windows operating environment with complete
functions
Fully automatic ignition gas circuit intelligent control, software
ignition, more convenient
The safety includes cooling water protection, argon protection and
arc extinguishing protection. It is safer to use multiple shielding
and good grounding to make the instrument radiation less than 2V/m
(less than 10V/m according to JJG768-2005). Better ensure the
safety of operators.
