一、工作原理

　　声波在空气中速度为340米/秒，在水中为1500米/秒左右。声波在水下往返750米正好是1秒钟，测量声波的往返时间，

　　可以计算水下目标深度。超声波是频率高于人耳听力的声波，适合于水下探测。

　　测深仪通过超声波换能器，既发射超声波，也接收超声波，通过记录将水下目标显示在液晶屏上，计算出水底深度进行显示。

　　二、技术参数

　　1、采用分辨率字符型中文LCD液晶屏，数字、图形显示

　　2、高亮度LED背光;

　　3、自动量程跟踪测量，能实时、精确、稳定地测量

　　4、显示：水深、水温、水中障碍物显示

　　5、声呐频率200KHZ

　　6、盲区：小于≤0.5m(标准环境)

　　7、自动温度显示、温度补偿计算

　　8、量程150m。精度：1%

　　9、工作9V(锂电池或者叠层电池)

　　10、温度、水深英制、公制可切换

　　11、仪表尺寸205*55mm,带挂绳

　　12、声呐角度18±2(或者30°可选)°

　　13、整机(IP6X防护等级)水下耐压60米

　　14、电池工作时间：≥6h
