Dissolved Oxygen Sensor Oxygen Probe Sensor for Fisheries Factory Price
Product Overview
- IOT-485-DO is a digital dissolved oxygen (DO) sensor/probe by BOQU (Shanghai Boqu Instrument). It measures dissolved oxygen (0–20 mg/L) and temperature (0–65 °C) and outputs data via standard RS485 Modbus. The unit is industrial-grade (SS316 housing, graphite electrode), IP68 rated, and supports remote setup and calibration.
Product Features
- Measurement: DO range 0–20 mg/L, resolution 0.01 mg/L; temperature resolution 0.1 °C; accuracy ±0.2 mg/L and ±0.5 °C.
- Digital communication: standard RS485 Modbus for reliable industrial networking.
- Built-in temperature probe with instant temperature compensation and strong anti-interference performance.
- Robust construction: SS316 housing, graphite/steel-grit electrode film for harsh environments, IP68 protection.
- Flexible cabling: standard 5 m cable (extendable) with maximum transmission up to 500 m; power 9–36 V DC.
Product Value
- Provides accurate, stable long-term DO and temperature data to support process control and environmental compliance.
- Reduces operational downtime and maintenance through robust materials, stable electronics, remote calibration, and strong anti-interference design.
- Enables integration into SCADA/PLC systems via RS485 Modbus for centralized monitoring and data logging.
- Cost-effective option with factory-direct positioning for users needing industrial performance at competitive pricing.
Product Advantages
- Industrial reliability: corrosion-resistant SS316 body, durable electrode, and IP68 protection for immersion and harsh conditions.
- High signal integrity: digital RS485, independent anti-interference chip, and up to 500 m transmission minimize data loss and wiring limitations.
- Ease of use: remote configuration/calibration and plug-and-play installation lower commissioning time.
- Accurate control: built-in temperature compensation and fine resolution improve process control and product quality.
- Versatile power range (9–36 V DC) and standard process connection (Upper G1”) simplify integration.
Application Scenarios
- Aquaculture and fisheries (real-time DO monitoring for fish/shrimp farming).
- Wastewater treatment and environmental monitoring (effluent and surface water DO control).
- Industrial processes: chemical, fertilizer, metallurgy, and thermal power plant water systems.
- Food, beverage and fermentation/brewing industries (oxygen control during production).
- Pharmaceutical, biochemical and tap water systems where reliable DO measurement is required.
