L360 Acid Analyzer
The online L360 Acid analyzer titrates acidity in process streams emulating a benchtop colorimetric titration. All aspects are automated, including sampling, reagent addition, titration and cleanup. With every new sample the optical path is wiped clean prevent drift. For dependable process control, each result is checked for consistency and range prior to posting, alarming, or actuating controls. Detection and alarming of maintenance items, sample flow, and reagent supply are included. Reagent consumption is minimized with microliter fluid delivery. Grab sample and auto standard validation are available as an option. Output options include Modbus, current loop, and relay.
L360H has configuration of Base model with single stream inlet, precision burette for sample and reagents, process alarm relay.
Options
- AV Auto validation on bottled standard with reporting and alarming
- CL Current loop output, 4-20 mA
- DI Digital input for remote control of analyses
- ER Extended analysis range. For analyses beyond standard ranges.
- GS Grab sample or standard inlet
- MB Modbus RTU output for results, history, and alarms
- PCS Windows™ process overview and analysis configuration software
