CZJ-1 type proton magnetometer for wellboreDetailed product description：

CZJ-1 proton magnetometer is a downhole magnetic measurement instrument developed on the basis of ground proton magnetometer. Mainly used for deep mineral exploration, especially for searching for weakly magnetic ore bodies with magnetic anomalies of only tens to hundreds of newtons, such as non-ferrous metal deposits or precious metal deposits. In the process of mineral exploration, the combination of downhole proton magnetometer exploration and ground exploration will play an important role.
