L360 온라인 크롬6가분석기 (online L360 Cr(VI) analyzer)는 DPC 비색계 EPA 표준 방법 3500 Cr B를 사용하여 프로세스 스트림에서 6가 크롬 (hexavalent chromium)을 측정합니다. 매 측정 시 optical path를 깨끗이 클리닝하고 재보정하여 드리프트를 제거합니다. 샘플링, 시약 추가, 적정 및 클리닝을 포함한 모든 측면이 자동화됩니다. 신뢰할 수 있는 프로세스 컨트롤을 위해 posting, 알람, 또는 컨트롤 전에 각각의 결과에 대한 일관성과 범위를 확인합니다. Sample flow 및 시약 공급 (reagent supply)에 대한 자동감지, 이에 따른 알람이 포함됩니다. 마이크로 리터 fluid delivery로 시약 소비가 최소화됩니다. 샘플 수집 (grab sample) 및 auto standard validation이 옵션으로 제공됩니다. Modbus 및 current loop, relay 출력 옵션이 있습니다.
L360 온라인 크롬6가분석기는 기본 모델에 single stream inlet, 시료 및 시약 용 정밀 뷰렛, 프로세스 알람 릴레이로 구성되며, 다양한 옵션을 제공합니다. L360 시리즈 특징과 L360 온라인 크롬6가분석기의 사양을 확인하세요.

L360 Cr(VI) Analyzer
The online L360 Cr(VI) analyzer measures hexavalent chromium in process streams by means of DPC colorimetric EPA standard method 3500 Cr B. With every reading the optical path is wiped clean and recalibrated to eliminate drift. All aspects are automated, including sampling, reagent addition, titration and cleanup. For dependable process control, each result is checked for consistency and range prior to posting, alarming, or actuating controls. Detection and alarming of sample flow and reagent supply are included. Reagent consumption is minimized with microliter fluid delivery. Grab sample and auto standard validation are available as an option. Output options include Modbus, current loop, and relay.
L360Cr(6) analyzer has configuration of Base model with single stream inlet, precision burette for sample and reagents, process alarm relay.
L360 Cr(6) Options
- AV Auto validation on bottled standard with reporting and alarming
- CL Current loop output, 4-20 mA
- DI Digital input for remote control of analyses
- ER Extended analysis range. For analyses beyond standard ranges.
- GS Grab sample or standard inlet
- MB Modbus RTU output for results, history, and alarms
- PCS Windows™ process overview and analysis configuration software
- RO Relay output, form C, for process alarm, with configurable setpoint
- SAn Multi-stream sampling, n = number of streams.
- SB Sample strainer with auto backflush.
- SK Spares kit (basic and extended versions available)
- SP Sample pumping. For non-flowing samples.
