Terraprobe电子探测仪是一种配备有探针的手控装置。勘探者将探针插入地层,探针碰到任何金颗粒就会从扩音器或耳机内发出一种音响信号,并且控制盘上亮灯。该仪器含有一电子部件,一个带有硬金属尖端的测管,以及伸长管。位于尖端的传感器测量所碰到的每个金属颗粒的电位与导 The Terraprobe Electronic Detector is a hand-controlled device equipped with a probe. When the prospectus plunges the probe into the formation, the probe touches any gold particles and emits an audible signal from the megaphone or headset, illuminating the control panel. The instrument contains an electronic part, a test tube with a hard metal tip, and an extension tube. The tip-located sensor measures the potential and conduction of each metal particle it encounters
