L450 CO3 - Carbonate Analyzer
The online L450 carbonate analyzer measures alkalinity in processes by means of a dependable differential endpoint pH titration. With differential endpoint detection, the unit’s pH electrode does not require calibration or refilling. Multiple-break titrations are also possible for measuring multiple species, allowing separate determination of hydroxide and carbonates (OH- and CO3-). Auto detection and alarming of sample and reagent supply is included. For dependable process control, each analysis is automatically replicated and/or range checked prior to posting, alarming, or replenishing.
L450 CO3 has configuration of Base model with standard precision (20 µl) titrant dose pump, single stream inlet, 4-20 mA output, and one alarm relay output.
Options
CS Cyclone sample stream particle separator
DI Digital input for remote control of analyses or replenishment
ER Extended analysis range. For analyses beyond standard ranges.
GS Auto grab sample with sipper tube inlet
HP High precision titrant pump
PC Windows™ PC analysis configuration software
RP–p–n Replenishment (solenoid, burette, or pneumatic pump options)
SA–n Multi-stream sampling, n = number of streams.
SB Sample strainer with auto backflush. For particulate more than 20μm.
SK Spares kit (basic and extended versions available)
