Product Features
- High‑intelligence measurement: High‑precision AD conversion and single‑chip microcomputer technology realize stable dissolved‑oxygen measurement.
- Multilingual menu: Freely switch between Chinese and English display menus.
- Data logging: Built‑in memory stores up to one‑year historical data. Historical records can be exported via mobile‑phone APP through Bluetooth (optional function).
- Acousto‑optic alarm: Equipped with buzzer and alarm indicator lights; triggers sound‑light alerts when measurement values cross alarm thresholds.
- 4‑20 mA isolated current output: Output values can be arbitrarily configured or reversed for convenient site control; optocoupler isolation brings strong anti‑interference performance.
- Relay control: Supports interval relay control and random‑value display functions for special‑condition use.
- Display: 3.5‑inch 480×320 IPS color LCD screen with clear long‑distance viewing effect.
- RS485 communication: Adopts Modbus‑RTU protocol for connection with computers, PLC or DCS systems for data acquisition.
- Industrial watchdog: Prevents instrument freezing during long‑time operation.
- Built‑in real‑time clock: Supports time display for recorded data.
