L450 Ammonia Analyzer
The online L450 Ammonia analyzer measures ammonia in water using an ammonia gas sensing electrode. Alkaline pH adjustment is included to convert and release the ammonia for detection. Temperature correction is included for maximum accuracy. The electrode does not require manual calibration – automatic calibration with NH4Cl is included. No colorimetric indicator or pH electrode is required. For dependable process control, a changed analysis trend can be automatically retested prior to posting or alarming. For sample with particulate, a sample strainer with automatic backflush is offered. Sample conditioning systems are offered to meet many various requirements.
L450NH3 has configuration of Base model with two low-maintenance dose pumps for alkali and calibration standard, one sample/waste pump, single stream inlet, 4-20 mA output. Automatic temperature correction, automatic ammonia sensor calibration, reagent empty alarms.
Options
DI Digital input for remote control of analyses or replenishment
EB Ethernet server for remote monitoring via web browser
GS Auto grab sample with sipper tube inlet.
MS Multi-stream sampling
SB Sample inlet strainer with auto backflush.
