L450Zn At Line Zinc Titrator
The L450Zn at line nickel titrator measures zinc ion concentration in water, wastewater, or process streams by means of a robust EDTA titration. Its differential redox endpoint detection method eliminates the need for sensor calibration or replacement. Because peristaltic pumps and colorimetric dyes and indicators are not utilized, maintenance and reagent costs are minimized.
L450Zn At Line Zinc Titrator has configuration of Base model with one standard precision titrant dose pumps, single stream inlet, and flow-thru sample capture.
Options
- AE Eductor pump option. Used in place of electric pump.
- GS Grab sample capability. Sipper tube inlet.
- HP High precision. 0.1 µl resolution titration burette.
- MSx Multi-stream, x = number of streams.
- WF Auto water back flush of sample filter. (Use with -EP.)
- WM Windows™ Process Manager PC software
