L460 Silica LR A Analyzer

The low range L450 Silica LR analyzer measures silica in water by means of the proven Heteropoly Blue method with pH buffering. 1 Citric acid is used to destroy interfering phosphate complexes. A reducing agent is used to develop an intense blue color for this low range analysis. For dependable process monitoring, each analysis is automatically replicated prior to posting or alarming. Process level relay(s) with settable trip point and a maintenance alarm relay are provided. Low drift is accomplished by auto-corrections for reaction rate and optical clarity. Sample is drawn from pressurized streams or loops. For sample with significant particulate, a sample strainer with automatic backflush is offered. An optional grab sample port is offered.

L450-Silica LR has configuration of Low range colorimetric silica analyzer with multi-stream options. Process alarm relays included.

 

Options

  • DI Digital input for remote enable of analyses or dosing
  • DO Digital output relay with settable trip point or other control function
  • EB Ethernet server for remote monitoring via web browser
  • GS Auto grab sample with sipper tube inlet.
  • MS Multi-stream sampling
  • PV Current loop process value output
  • SB Sample inlet strainer with auto backflush
