RESEARCH DIRECT-READING
SPECTROGRAPH by Baird-Atomic Combines the versatility of a spectrograph and the speed and precision of a direct reader. •
Easy conversion between photographic and direct reading accomplished in minutes.
• Fast routine analysis by direct reading approach - r e s u l t s in minutes - p r e c i s i o n permits analysis of high alloys. •
Frees spectrograph for research and non-routine investigations.
•
Direct reading features can be added later in field — you can buy spectrograph now, direct reader later.
