Groundwater Gamma and Long-Short-Normal Resistivity Logs Estimate Ground Water Quality and Aquifer

JHQ - 2D is a digital logging system specially designed for the convenience of field work, which can connect with various kinds of pipe and log. Because this system uses a series of advanced technology, it improves the use of one ground-based instrument controlling one heavy logging probe into one ground-based instrument controlling various kinds of logging probe, it also includes the deep measurement, the power supply and so on. The instrument has a light weight and simple operation and maintenance, which can be connected to the tube type, which can be aseismatic, temperature-resistant, moistureproof and high reliability.

Parameter

1. The use of the environment:Power supply: 220V, 50 Hz;Using the environment temperature: -20℃ ~ 45℃;Using the environment humidity: 90% or less (45℃)
