L450 H2O2 Analyzer
The online L450 H2O2 analyzer measures hydrogen peroxide in process streams by means of a robust, differential endpoint titration with ceric sulfate in acid solution. With the differential method the analysis is immune to sensor drift. And no sensor replacement, refilling, or adjustment is required. Reference electrode does not require replacement. No peristaltic pump is used. Auto detection and alarming of sample and reagent supply is included. For robust process control, each analysis can be automatically replicated and/or range checked prior to posting, alarming, or replenishing.
L450 H2O2 analyzer has configuration of Base model with one standard precision (20 µl) titrant dose pump, one acid reagent pump, single stream inlet, 4-20 mA output, and one alarm relay output.
Options
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
PCS Windows™ process overview and 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) SP Sample pump. For unpressurized samples.
