IP68 Waterproofing & High-Pressure Reliability Testing

  • Hydrostatic Pressure Test: Every unit is subjected to rigorous pressure chambers, simulating depths up to 100 meters to ensure the housing remains perfectly sealed under extreme subsea loads.
  • Redundant Sealing Tech: We utilize double-layer O-ring gaskets and vacuum-molded seals to prevent saltwater ingress even in high-pressure marine environments.
  • Corrosion-Proof Integrity: The 316 stainless steel or high-impact ABS enclosure is treated with anti-corrosion coatings, ensuring zero oxidation after prolonged submersion.
  • Reliability Simulation: Our internal test chambers verify that all electronic components remain dry and functional under constant, deep-water immersion.
