Waltron 9031CX/9033X/9035 Sodium Analyzer

Features

• 0.10ppb to 10ppm
• ±5% of reading or ±0.1ppb to (whichever is greater) within ±5°C of calibration temperature accuracy
• ± 5% of reading or ± 0.1ppb (whichever is greater) at constant temperature reproducibility
• 90% of 10 – 1ppb step: less than 3 minutes; 90% of 100 – 1ppb step: 5 minutes response time
• Automatic temperature compensation
• Alkaline vapor buffer:0.88 SG (28% to 30% NH3) ammonia above 0.5ppb sodium, 99% diisopropylamine solution below 0.5ppb sodium pH compensation
