国外推出一种新型的地下水探测器(图1),可用于探测地下水(或碳氢化合物液体,如油)的水位、厚度、水温、pH值、溶解氧、绝对电导率等参数。该探测器主要由测带、探头、附件构成。整个装置的体积(高、宽、厚)为12×104×英寸。测带:此系钢制卷尺(图2),带长100英尺, A new type of groundwater detector (Figure 1) is introduced abroad to detect parameters such as water level, thickness, water temperature, pH, dissolved oxygen, and absolute conductivity of groundwater (or hydrocarbon fluids such as oil). The detector is mainly composed of tapes, probes and accessories. The whole device’s volume (height, width, thickness) is 12 x 104 x inches. Test tape: This is a steel tape measure (Figure 2), with a length of 100 feet,
