DWG5301

DWG5301 is a sodium plasma monitor which can be use to test ppb level, professional polarographic measurement for electrodes, automatic constant pressure of the fluid current system and stability of the high-alkaline system to ensure the stability of the measurement. It can be widely used for thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and water solution such as sodium continuous monitoring.

The main Features:

Display: LCD

Computerized high-performance CPU chip, high-precision AD conversion technology, SMT technology, multi-parameter measurement, temperature compensation, self-test instrumentation, high accuracy and repeatable.

High reliability: mono-board structure, touch-button and no switch knob.

Rapid response, accurate measurement and stability.
Automatic constant pressure and current: automatic compensation for water flow and pressure.
High-performance and stability of the alkalization system: a new system to add water and alkaline reagent, matching alkalization effect by air pump, can be used in high acidity of sodium in positive-bed water.

Professional electrode for ppb measurement.
Dust and water proof design: protection rate IP65, suitable for outdoor use.
Electromagnetic compatibility (EMC/RFI) design: according to European standards EN50081/50082

Terminal Automatic Alarm

Web features: isolation of the current output and RS485

History curves: After every 5 minutes machine will record a curve and this process will continue for one month.
Notepad: It can record 200 pieces of information.

Real-time clock (Built-in): to provide a kind of functions, such as the benchmark time. Industrial-control watchdog: to ensure that the instrument will not breakdown.

Password: Calibration, parameters set up and maintaining are protected by password.

Real-time Surveying: Instead of sodium meter, it can be used to measure the performance of standard solution.
