Overview

The Industrial Soil Oxygen O2 Sensor is a premium, high-precision instrument engineered for continuous, real-time tracking of subsurface oxygen concentrations. Operating across a 0-25%,vol range with a remarkable ±2%{F.S.}, accuracy, this robust sensor is custom-designed to monitor root-zone respiration and soil health.Featuring comprehensive multi-signal output compatibility (including RS485 Modbus-RTU, 4-20mA, and 0-5V/0-10V), it integrates seamlessly into existing data loggers, PLC systems, and automated smart agriculture frameworks. Built to withstand harsh environments with premium anti-corrosion materials and an internal temperature compensation module, it guarantees long-term stability and minimal maintenance for commercial greenhouses, agronomy research, and environmental monitoring.

Feature

Multi-Protocol Integration: Supports standard Modbus-RTU over RS485 alongside analog legacy signals (4-20mA, 0-5V, 0-10V) for ultimate telemetry flexibility.

Built-In Temperature Compensation: Integrated thermal sensor automatically calibrates readings against soil temperature fluctuations, preventing seasonal drift.

Industrial-Grade Durability: Encased in heavy-duty, anti-corrosion housing to resist moisture, soil acids, and harsh fertilizer environments for an extended service life.

Ultra-Low Power Design: Optimized for power-constrained IoT remote stations and continuous solar-powered data logging deployment.

Rapid Response & High Resolution: Delivers immediate detection of subtle O2 dynamic changes, even in compacted soil or low-oxygen root environments.
