Main Technical Parameters of HFD-C Groundwater Detector:
2. Brief Introduction:
The HFD-C Multi-Function Natural Electrical Field Detector is specifically designed for underground water detection at depths of up to 300 meters. It measures the intensity of the natural electrical field to monitor changes in underground resistivity, helping locate and determine the depth of groundwater.
This instrument solves a major challenge in natural electric field surveys—frequency selection and interference suppression. With its waterproof casing and touch screen interface, it’s easy to handle and simple to use.
Compared to traditional DC electrical water detectors, the HFD-C offers significantly faster measurement speeds and is much lighter. In the past 20 years, we’ve built a strong reputation among our customers.
