L300 pH At Line pH Monitor 인라인 pH 측정기

L300 pH Monitor는 하나 이상의 샘플 스트림에서 시료를 채취합니다. Flow-thru 분석을 위해 시료를 가압하거나 선택적으로 L300으로 끌어들입니다. 정확성과 신뢰성을 위해 각각의 측정이 반복적으로 수행됩니다. 기본적으로 측정 후 샘플은 세척되어 시스템으로 부터 배출됩니다. 아울러, 온도보정과 온도제어, 샘플 컨디셔닝, 시약 세척이 설정된 대로 수행됩니다. 공정 별 성능을 위해, 샘플링 간격 (sampling interval), 샘플 flow time, 침지 시간 (immersion time), 교반 속도, 최소 판독 안정성 및 반복성, 용액 온도 계수가 구성 가능한 설정에 포함됩니다.

Liquid Analysis Systems사의 L300 pH 모니터는 완전 자동화된 pH 보정 및 single, multi-process  stream으로 pH를 측정합니다. 

완전 자동화된 센서 교정 및 클리닝으로 센서의 수명을 수 배로 늘리면서, 옵션인 샘플 전저리 스텝을 거침으로써 공정 탱크나 파이프에서 측정이 아닌, L300 장치 내에서 pH를 측정하게 됩니다. 즉, 장기적인 안정성에 더불어 최소 운영 비로 완벽한 자동화가 구축됩니다.

 

L300 Series Features

  • Sensor performance monitoring
  • Reading stability and range alarms
  • Reagent supply alarms
  • Output options for recording, alarming, dosing, and/or replenishing

Through its display and keypad, users can view process status and history, and modify analysis intervals and other configuration parameters. Additionally, the user has the capability to operate hardware and to monitor operations. This series offers a variety of hardware options for stream selection, sample preparation, and sample/reagent delivery.

 

Series Options

  • Multi-stream analysis
  • Auto sample retrieval from non-pressurized sources
  • Grab sample port
  • Sample temperature control
  • Sensor and system reagent cleaning
  • Filter auto-backflush
  • RS 485/Ethernet networking or current loop outputs
  • Replenishment and dosing systems

 

L300 pH Monitor

The Liquid Analysis Systems’ L300 pH monitor performs fully automated pH calibration and measurement of single or multiple process streams. Measurements are performed within the L300 unit, not in the process tank or pipe, providing fully automated probe calibration and cleaning, extending probe life many fold, and permitting additional (optional) sample preparation steps. This accomplishes complete automation at minimum operating cost with long-term reliability.

The L300 pH selects sample from one or more sample streams. Sample can either be pressurized for flow-thru analysis or optionally drawn into the L300. Each reading is replicated for accuracy and reliability. Sample typically is rinsed and purged from the system after each set of readings. Temperature correction, temperature control, sample conditioning, and/or reagent cleaning are also performed, as specified. For process specific performance, configurable settings include sampling interval, sample flow time, immersion time, stirring rate, minimum reading stability and repeatability, and solution temperature coefficient(s).

L300 pH Base Model has configuration of Base model in windowed fiberglass enclosure with single sample inlet, two pH buffer channels, pH measurement cell with pH and temperature sensors, magnetic stirrer, and rinse/purge system.

 

L300 pH Monitor Options

  • AB Sample strainer with automatic back flush
  • DI Digital input for remote enable of analyses or dosing
  • ES Ethernet server for remote operation
  • GS Auto grab sample capability. Sipper tube inlet.
  • RPSn Replenishment pump (Solenoid, Burette, or Pneumatic options)
  • SAn Stream addition, n = number of streams.
  • SD Sample drawing system: for non-pressurized sample
  • SK Spares kit (standard and extended versions available)
