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.
