Our advantages

Over the years, Puqi focuses on Hydrogeological exploration, Intelligent data-capture technology and Application of special technique, carrying out Scientific research, Technical services and Marketing application. We have completed more than 65 items including National ministries, Sino-foreign cooperation and major scientific research projects. Having the honour to win a number of national research awards, with more than 117 national patents.

1. High Measurement 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 is improved about 10 times more

than traditional resistivity method.

2.Convenient to Carry

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

3.Simple operation

Equipment is automatically controlled by micro PC. You can learn its operation in 10 minutes. It

will take 10 minutes for persons without prospecting experience to finish training.

4.Good performance and high Accuracy.

The resolution of measurement is up to 0.001mV, and precision is 2%. It gains high stability and a
bnormity curves matching with that of traditional geo-electrical equipment in lots of field survey.

5.Strong 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 weak signal area, city, high electric jamming

area and working area with other exterior interference via frequency selector and digital

processing.

6.The unique feature of Automatic mapping

This instrument can automatically form curve graph and profile map with one button after

completed recording data, no need transfer the data to computer for drawing mapping

After-sales service

1. Two year guarantee-if using of the product is influenced due to quality problem, you may receive guarantee of the product at the service network within 2 years after the date of purchase.

2. Lifetime maintenance-lifetime maintenance service is implemented on all factory series products. We offer maintenance of machine which surpasses the maintenance period or has manual damage with material and labor charges.
