Product Overview
As the core component of soil temperature and humidity sensor probe that directly touches the soil, its design and material directly affect the measurement accuracy and durability. Here are the key features and technical details of the probe:
1. Material composition
Main material : 316L stainless steel (resistant to acid and alkali corrosion, suitable for saline-alkali land) or special alloy to ensure long-term burial resistance.
2. Sealing process: epoxy resin vacuum potting to achieve IP68 waterproof and dustproof to prevent electrolyte penetration and damage to the circuit.
3. Anti-corrosion and durability reinforced design
Chemical resistance
Surface coating (e.g., gold/nickel plating) against strong acids (pH<4), alkali (pH>9) and highly salty soils (conductivity ≤20,000 μS/cm).
Saline adaptability: Frequency-domain reflectometry (FDR) technology reduces ionic interference and controls humidity error within ±3%.
4. Mechanical protection
Probe tip hardened to withstand crushed stone extrusion (compressive strength ≥30MPa)
Spiral electrode designs (such as tubular moisture meters) disperse stress and avoid bending and fracture.
