SJG-9435A type dissolved oxygen analyzerDetailed product description：

Characteristics of SJG-9435A Dissolved Oxygen Analyzer:

The structural characteristics of the instrument are disk mounted, dry and wet separated structure, which is easy to install, operate and maintain
The instrument displays in a backlit dot matrix format, using a Chinese menu, and simultaneously displays the dissolved oxygen concentration (μ g/L) and water temperature value (℃) of the tested water sample
It has a (4-20) mA DC isolated output signal, and the corresponding upper and lower limits of dissolved oxygen concentration output can be arbitrarily set within the range of (0-200) μ g/L
It has an upper limit alarm function. Contact capacity 2A, 220V AC (no inductance)
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
Equipped with automatic range switching function for (0-20) μ g/L, (0-200) μ g/L, (0-2.00) mg/L, and (0-20) mg/L (for calibration)
Equipped with automatic zero calibration, full calibration, air pressure calibration, and automatic temperature compensation functions
The protection level of the electronic unit chassis is IP65, which can prevent water spray and dust intrusion
Equipped with RS-232 or RS-485 output interface, capable of digital output
Measurement pool material: Organic glass.
