The L510 Anodizing Line Controller automates sampling, analysis, reporting, and (optionally) replenishment an anodizing line including the clean, etch, deoxidize, anodize, dye, and seal steps. The controller uses known and reliable pH and ORP/redox titrations. Both absolute (calibrated) and differential endpoint detection methods are included for delivering long term accuracy and consistency. Differential endpoint detection in particular maximizes immunity to sensor drift. All analyses are checked for repeatability, range, and tread, and, if necessary, are replicated for verification. Replenishment is initiated only after all user-configured checks are passed, including volume limits and/or operator approval.
Liquid Analysis Systems’ L510 series process controllers accomplish complete process line automation with analysis, replenishment, and reporting. The L510 series controllers are optimized for year-round reliability, ease of use, and low operating cost. Model L510ALC has configuration of Base model with one titration cell; pH, Pt, and reference sensors; microliter range dose pumps; venturi-driven sampling/waste pump; sample selection valves; and sample and reagent detectors.

Series Features:
- Online titrametric pH & ORP analyses
- Auto sample retrieval and preparation
- Auto pH calibration
- Auto check of titrant and sample
- Auto repeatability, range, and trend checks
Through its display and keypad or optional Ethernet interface, users can view process status and history, and modify analysis intervals and other configuration parameters. This L510 offers a variety of hardware options for stream selection, sampling, sample preparation, and sample/reagent delivery to accommodate specific customer requirements.
