*Main Features of the Underground Water Detector:
1. All-in-one functionality: Combines long lead IP instrument, 2D high-density resistivity meter, 2D high-density IP instrument, and medium-power short lead transmitter in one device.

2. Easy to use: Features all-digital automatic measurement, automatically compensating for spontaneous potential, drift, and electrode polarization. Large-screen LCD display supports Chinese characters, allowing over 14 wiring modes to be displayed directly in high-density mode. In DZD-6A standalone mode, nine electrode arrangements can be shown, and real-time curve display is possible during operation.

3. Large storage capacity: Stores up to 120,000 measuring points in high-density mode and 4,800 points in DZD-6A standalone mode. Each point contains 22 digits, and data can be transferred via RS-232 serial interface for digital interpretation using appropriate software.

*Main Applications of the Underground Water Detector:
1. High-resolution research, tomography, and monitoring.
2. Coal mining gobs, caves in Custer areas, and geological disaster surveys including landslides.
3. Engineering geological exploration such as factory foundations, highways, bridges, railways, civil works, hydrology, and environmental projects.
4. Landslide and other geological disaster investigations.
5. Metal and non-metallic mineral resources exploration and geothermal surveying.

Stainless Steel Products

304 stainless steel has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. Hot-rolled stainless steel is an alloy steel that is not easy to rust, but not absolutely rusted. Cold-rolled stainless Steel Plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to a steel plate that is resistant to chemical corrosive media such as acid, alkali, and salt.
