L450 Thiocyanate Analyzer
The online L450SCN analyzer measures thiocyanate in water by means of a precise and reliable potentiometric titration. With differential endpoint detection, the electrode does not require calibration, and sensor drift common with other methods is eliminated. No colorimetric indicator is required. For dependable process control, each analysis is replicated and/or trend checked prior to posting, alarming, or replenishing. Sampling can be drawn from pressurized sample stream or open tank. For sample with particulate, a sample strainer with automatic backflush is offered. For heated samples, sample cooling is offered to achieve sharp endpoints and optimally precise results.
L450SCN has configuration of Base model with standard precision (20 µl) titrant dose pump, one sample/waste pump, single stream inlet, 4-20 mA output.
Options
DI Digital input for remote enable of analyses or dosing
DO Digital output relay with settable trip point or other control function
EB Ethernet server for remote monitoring via web browser
G1 Auto grab sample with sipper tube inlet
MS Multi-stream sampling
RR/P Replenishment control (Relay or Pneumatic output options)
SB Sample inlet strainer with auto backflush.
SKB/E Spares kit (Basic or Extended version)
