L460Cr - Total Chronium Analyzer

The at-line L460 analyzer measures total chromium in water by means of chromic conversion and the proven, EPA-approved DPC colorimetric method for chromate. As an option, the sample can be diluted automatically to extend the analysis concentration range. The procedure includes pH buffering and sample turbidity compensation. For dependable process control, each analysis can be automatically replicated and/or trend checked prior to posting, alarming, or replenishing. Sampling can be drawn from pressurized sample stream or pumped from overflow sampler. For sample with particulate, a sample strainer with automatic backflush is offered.

L460Cr analyzer has configuration of Colorimetric at-line analyzer with 540 nm optical sensor, sample capture cell, standard precision (20 µl) reagent dose pumps, single stream inlet, 4-20 mA output.

 

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
  • ER Sample diluter for extended analysis range
  • GS Auto grab sample with sipper tube inlet.
  • MS Multi-stream sampling
  • SD Sample diluter for extended analysis range
  • SB Sample inlet strainer with auto backflush
  • SP Sample pump for unpressurized samples
