Wholesale Dissolved Oxygen Analyser for Plants
Product Overview
1) Product overview
Product Features
- DOG-2092Pro Wholesale Dissolved Oxygen Analyser for Plants is a continuous, precision meter for dissolved oxygen (DO) and temperature monitoring.
Product Value
- Measurement ranges: 0.00–20.00 mg/L DO, 0.00–200.00% saturation, temperature -10.0 to 130.0 °C.
Product Advantages
- Compact, panel/wall/pipe-mountable unit with ABS (V0) flame-retardant housing, IP65 protection, and multilingual interface (English / 简体中文).
Application Scenarios
2) Product features
- High-precision sensing: DO accuracy ~1% and temperature accuracy ±0.2 °C.
- Fast response, long probe life and no sensor warm-up required.
- Outputs and control: two isolated 4–20 mA outputs, RS485 Modbus RTU communication, and two programmable relays (5 A @ 250 V AC / 5 A @ 30 V DC).
- Temperature compensation options (PT1000 / NTC10K / 22K), wide AC input (90–260 V AC), low power consumption (~4 W).
- Compact footprint (98.2×98.2×128.3 mm, cutout 92×92 mm) and IP65 protection for harsh environments.
3) Product value
- Ensures water quality and safety by maintaining appropriate DO levels for drinking water, wastewater and process streams.
- Supports regulatory compliance for discharge limits and environmental protection.
- Optimizes biological and chemical treatment processes (improves process control, efficiency and product quality).
- Prevents oxidation-related damage in industrial systems (e.g., steam generators), helping reduce maintenance costs and downtime.
- Enables automation and remote monitoring via Modbus and 4–20 mA outputs for better operational decisions.
4) Product advantages
- Reliable, stable continuous measurement suitable for industrial environments.
- Multiple I/O and control options (dual 4–20 mA, RS485, two relays) for easy integration into control systems and alarms.
- Rugged, flame-retardant, IP65 enclosure with flexible mounting (panel/wall/pipe).
- Fast response and long probe life lower operating costs and maintenance frequency.
- Backed by BOQU’s service network, training, testing resources and timely customer support.
5) Application scenarios
- Industrial wastewater treatment and discharge monitoring.
- Drinking water production, biofiltration and environmental water quality monitoring.
- Ultrapure water systems and contamination-sensitive processes.
- Fermentation, food & beverage production and other biological process controls.
- Industrial processes sensitive to oxygen (power plant deaeration/steam systems), aquaculture and laboratory monitoring.
