Detailed Description

1.Product overview:

Utilising imported components and dissolved oxygen membrane heads, this instrument is based on new polarographic analysis technology, advanced manufacturing processes, and surface-mount technology. By employing these advanced analytical techniques, the instrument ensures long-term stable, reliable, and accurate performance. It features Chinese menu-driven operation, notebook storage of measurement data, and 485 communication functionality. It is widely applicable for continuous monitoring of dissolved oxygen levels in solutions across industries such as chemical fertilisers, metallurgy, environmental water treatment, pharmaceuticals, biochemistry, food processing, aquaculture, and municipal water supply.

2.Product Features

• Large-screen dot-matrix LCD display with Chinese menu-based operation.
• Simultaneous display of multiple parameters: dissolved oxygen levels, temperature, output current, alarm points, etc., displayed concurrently for intuitive readability, with range-out-of-limit alerts.
• Screen displays alarm status and can simultaneously output switch ON/OFF signals.
• Automatic temperature compensation function: automatic 0–60°C.
• Communication function (optional): features an RS-485 communication interface (partially compatible with MODBUS protocol), and the DO value corresponding to the 4–20 mA current output can be arbitrarily set.
• Notebook: can store 50 measurement data points, allowing users to record measurement data.
• Arbitrary hysteresis setting function to prevent frequent switching of the relay.
• Watchdog function: Ensures the instrument does not freeze.
• Imported core components.
• Can be restored to factory settings, with power failure protection exceeding 10 years.
