L450SO2 온라인 분석기는 견고한 요오드 산화 환원 적정 (iodometric redox titration)을 통해 물이나 폐수, 다양한 공정 중에 SO2 (또는 H2SO3) 농도를 측정합니다. 채용된 시차 종말점 검출 (differential endpoint detection) 시 센서의 드리프트 영향을 받지 않습니다.
L450SO2-121 분석기는 기본 모델에 1 개의 샘플 주입 펌프 (sample dose pump), 2 개의 정밀한 표준 시약 주입 펌프 (KI-KIO3, H2SO4), 샘플 추출기 (sample eductor) 및 single stream inlet으로 구성되며, 다양한 옵션이 제공됩니다. L450 시리즈 특징과 L450SO2-121 아황산 측정기 모델 사양을 확인하세요.
Liquid Analysis Systems사의 L450 series 화학 분석기는 pH, ORP, ISE, 탁도계 및 다양한 센서를 사용하여 많은 수성 화학 종의 온라인 습식 화학 적정법에 따라 분석합니다. L450의 기능은 신뢰성 및 사용 편의성, 최소 운영 비용에 최적화되어 있습니다.

L450SO2 Online Sulfite Analyzer
The L450SO2 online analyzer measures SO2 (or H2SO3) concentration in water, wastewater, or process streams by means of a robust iodometric redox titration. The differential endpoint detections employed are immune to the effects of sensor drift.
L450SO2-121 analzyer has configuration of Base model with one sample dose pump, two standard precision reagent dose pumps (KI-KIO3, H2SO4), sample eductor, and single stream inlet.
L450SO2 Options
- AC Auto calibration from standard solution.
- CV Ceramic valves for high particulate tolerance.
- G Grab sample capability. Sipper tube inlet.
- HP (L500 model) High precision using 0.1 µl resolution titration burette.
- MSx Multi-stream, x = number of streams.
- SC Sample cooler -WF Auto back flush of sample filter
