L450 Cu Analyzer
The online L450 Cu analyzer measures copper in water by means of reliable and sensitive colorimetric analysis. With automatic background correction, sensor drift common with other methods is eliminated. The method comprises pH buffering, Cu reduction, and a digestion period for color development. To achieve dependable process control, each analysis is automatically replicated and/or trend checked prior to posting, alarming, or replenishing. Sample can be drawn from a pressurized sample stream or pumped from a process tank. For sample with particulate, a sample strainer with automatic backflush is offered as an option.
L450Cu has configuration of Base model with standard precision (20 µl) titrant dose pumps, single/waste pump, 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
PC Supervisory Windows™ PC software license
G1 Auto grab sample with sipper tube inlet
MS Multi-stream sampling
RR/P Replenishment control (Relay or Pneumatic output options)
SB Sample inlet strainer with auto backflush.
SKB/E Spares kit (Basic or Extended version)
