The PQWT-S500 (100/150/300/500M) is a Natural Electric Field Frequency Selection System geophysical instrument that utilizes the electrical differences in earth's natural magnetic field. It analyzes electromagnetic field frequency variations to study underground material changes and solve geological problems.

Measurement data is recorded in millivolt self-potential units. This fully automatic water finder is a portable deep measuring instrument.

• High Speed and Efficiency: Complete over 8000 meters of profile measurement daily, detecting geological abnormalities at various depths with 10x greater efficiency than traditional resistivity methods
• Portable Design: Weighs under 2kg with no heavy power supply required, using natural earth electric field low-frequency signals
• Simple Operation: Micro PC-controlled with 10-minute learning curve (30 minutes for complete novice training)
• Precision Measurement: 0.001mV resolution with ±2% accuracy, matching traditional geo-electrical equipment results
• Advanced Anti-Interference: Effective in weak signal areas, cities, and high electric jamming zones
• Automatic Mapping: One-button operation generates complete mapping without computer processing

• 2-year warranty covering quality issues
• Lifetime maintenance service
• 24-hour professional support
