EMGA 921 Hydrogen Analyzer

دستگاه آنالایزر هیدروژن مدل EMGA 921 برای تعیین درصد عنصر هیدروژن در نمونه‌های جامد و معدنی مورد استفاده قرار می‌گیرد که در آن نمونه کاملا ذوب می‌شود و سپس گازهای حاصل شده توسط ذوب شدن نمونه توسط آشکارساز TCD آنالیز می‌شود. مدل‌های EMGA 821M و EMGA 821AC نیز موجود می‌باشند که در مدل M دستگاه به صورت کاملا Manual کار می‌کند و در مدل AC دستگاه دارای Automatic Cleaner می‌باشد. اما مدل EMGA 921 دستگاه‌ رده بالای کمپانی HORIBA است که مدل فول محسوب شده و Automatic Cleaner و Crucible Loader را به طور پیش فرض دارد.
