SJG-7835A type hydrazine monitoring instrumentDetailed product description：

Characteristics of SJG-7835A Hydrazine 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 hydrazine concentration (μ g/l) and water temperature value (℃) of the tested water sample
It has a (4-20) mA DC isolated output signal, and its corresponding upper and lower limit values for hydrazine concentration output 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 state without calibration
The electrochemical measuring cell and gel electrolyte are used, which have fast response, accurate measurement and simple operation
The protection level of the electronic unit chassis shell is IP65, which can prevent water spray and dust intrusion
Equipped with RS-232 or RS-485 output interfaces, it can achieve digital output
Measurement pool material: Organic glass
