L460 Hardness Analyzer
The atline L460 Hardness analyzer measures water hardness by means of the proven Calmagite colorimetric method. The analyzer can be configured to measure and report calcium, magnesium, or both. For dependable process control, each analysis can be automatically replicated and/or trend checked prior to posting, alarming, or replenishing. Sampling can be drawn from pressurized sample stream or pumped from overflow sampler. For sample with particulate, a sample strainer with automatic backflush is offered.
L460CaMg has configuration of Base model with standard precision (20 µl) titrant dose pumps, 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
- GS Auto grab sample with sipper tube inlet.
- MS Multi-stream sampling
- SD Sample diluter for extended analysis range
- SB Sample inlet strainer with auto backflush.
