DWG-8025A Sodium Monitoring InstrumentDetailed product description：

Characteristics of DWG-8025A Sodium Monitoring Instrument:
Instrument structure features: disk mounted, dry and wet split structure, easy to install, operate and maintain
The instrument displays in a backlit dot matrix format using a Chinese menu, while also displaying the sodium ion concentration value (/1) and water temperature value (℃) of the tested water sample
It has a (4-20) mA DC isolated output signal, corresponding to the upper and lower limits of sodium ion concentration output, which can be set arbitrarily
Equipped with upper and lower limit alarm functions, with a contact capacity of 2A and 220V AC (non inductive)
Equipped with power-off data protection function, even if there is an abnormal power outage, the data stored inside the instrument is still valid. After restarting, it can enter the measurement without calibration
The instrument has a self diagnostic system that automatically determines the temperature of the solution, the performance of the electrode, the concentration of the standard solution, and the program for calibrating the solution
The instrument adopts the principle of secondary addition calibration to reduce errors caused by low concentration calibration
The instrument has automatic temperature compensation function
The protection level of the electronic unit chassis shell is IP65, which can prevent water spray and dust intrusion
Equipped with RS232 or RS485 output interfaces, it can achieve digital output

Measurement pool material: Organic glass
