Automatic constant pressure constant flow of liquid road system: automatic compensation water flow and pressure changes.
Stable, effective alkalify system: adopting new waterways and alkalify agent to join system, matching qibeng strengthen alkalify effect, can be used for Yang high acidity water bed sodium measurements.
Professional PPB measurement electrode.
Waterproof dustproof design: protection class IP65, suitable for outdoor use.
The electromagnetic compatibility (EMC/RFI) design: by European standards 50082 EN50081 / design and manufacture.
Alarm functions: alarm signal isolating output, alarm upper and lower limit can be arbitrary set, alarm lag withdrawn.
Network function: the isolation of current output and RS485 communication interface.
Historical curve: continuous record of a month data, five minutes a point.
Notepad function: record 200 information.
Manual current source: convenient records and detection device testing.
Built-in real time clock: provide various function of time benchmark, etc.
Industrial control type watchdog: ensure instrument won't crash.
Password management: parameter setting and maintain all have password protection.
But offline measurements: instead of laboratory sodium list, measurable standard fluid inspection instrument performance.
Use cost is low, the maintenance quantity was small.
