PQWT-TC1200.1500M Ground Water Detector

PQWT-TC1200.1500M automatic mapping water detector is based on the Earth's electromagnetic field as the field source, based on the difference in the conductivity of different underground geological structures, and by studying the variation law of the electric field components at different frequencies to study the geological structure and changes, to find groundwater resources by scientific method. Changes in geological structure are displayed in real-time through multiple curves. Automatic form mapping geological profile by one key operate easily, get rid of complicated computer graphics. The site can quickly understand the geological structure through the automatic mapping curve and profile, and analyze specific information such as aquifers, fractures, faults, and caves. The instrument is widely used in the rapid analysis of geological structure changes in different terrains such as plains, hills, mountains, plateaus, and basins to determine well locations, aquifers, and aquifer depth

Introduction to Instrument

The Instrument called as (Natural Electric Field Frequency Selection System) geophysical instrument, shortly known as frequency system.

Instrument working on the principle of electrical difference of natural earth magnetic field, the several different frequencies of electromagnetic field changes is the law to study the underground field material changes to solve the Geological problems.

The measurement data is Self-potential, and the unit is millivolt.

Main Features

1. High Speed and High Efficiency
Complete more than 8000 meters profile measurement in one day to realize geological abnormality in different depth, the prospecting speed and efficiency are improved about 10 times more than traditional resistivity method.

2. Easy to Carry
Without the heavy power supply, it uses low-frequency signals in earth natural electric field as the signal source,  and the complete set weight is less than 2kg so easy to carry

3. Simple Operation
Equipment is automatically controlled by the micro PC. You can learn its operation in 10 minutes.
It will take 0.5h for persons without prospecting experience to finish training.

4. Good Accuracy, High Accuracy
The resolution of the measurement is up to 0.001mV, and precision is ±2%.

It gains high stability and abnormity curves matching with that of traditional geo-electrical equipment in lots of field survey.

5. Anti-interference Ability
It has advanced anti-jamming technology and multiple anti-jamming designs. You can observe abnormity curves result with good repetition even in the weak signal area, city, high electric jamming area and working area with other exterior interference via frequency selector and digital processing.

6.A key to mapping
The detector is fully automatic form mapping after sampling data no need the computer drawing mapping
