Product Description
WDK-06 Industrial-grade Electrochemical Oxygen Gas Sensor For Environmental Monitoring
Core Features:
- Wide Environmental Adaptability: Operates stably in extreme temperatures (-30℃ ~ +70℃) and high humidity (5% ~ 95% RH), with IP67 protection for harsh industrial conditions.
- High Measurement Reliability: Adopts a high-performance electrochemical sensor with low drift (≤ ±0.3% FS/year) and high accuracy (≤ ±1.5% FS), ensuring long-term data validity.
- Flexible Integration: Supports multiple output signals (analog/digital/wireless) and mounting methods, compatible with most industrial control systems (PLC/DCS) and remote monitoring platforms.
- Safety Compliance: Optional explosion-proof design (ExdⅡCT6 Ga) meets safety standards for hazardous areas (e.g., chemical plants, oil refineries), reducing fire/explosion risks.
Typical Applications:
- Industrial process control: Fermentation tanks, thermal treatment furnaces, and gas mixing systems (monitoring O₂ to optimize production efficiency).
- Confined space safety: Mines, sewers, and storage tanks (early warning of low oxygen levels to protect personnel safety).
- Environmental monitoring: Greenhouses, clean rooms, and indoor air quality (maintaining optimal O₂ concentrations for plants or equipment).
- Energy industry: Natural gas pipelines, coal mines, and power plants (preventing oxygen-induced corrosion or explosion hazards).
