产品简介:SC-5F电容式数字显示水份测定仪,是SC-3B,SC-3F水份测定仪的升级版,采用两根不绣钢直接插入法测定粮食的含水量。比原先铜棒式插放法更难磨,显示器提供蓝屏显示,探头接触被测物便会夜光显示,使用户可在夜间操作.本机外观流畅,测试迅速、读数直观、携带方便。主要用于粮食收贮袋包监测,是收购粮食的理想设备。
技术性能:
1.测量品种和范围:(及其它颗粒状品种)水稻10-20%大米10-20% 小麦10-20%油菜5-20%玉米10-20%
2.精度:0.3%
3.响应时间:5秒
4.测量深度:30CM
5.工作环境:温度0-40℃,相对温度<85%
6.电源:6F22迭层电池一只(9V)
工作原理:
本仪器由电容传感器,C/V转换电路,A/D变换器和LCD数字显示电路组成.电容式传感器插入被测粮食后,其内介质就是被测各种不同粮食。由于水的介电常数比一般物质的介电常数大得多,所以被测粮食含水量只要有一微小的变化,就会引起传感器电容量有较大的变化。通过C/V转换电路及A/D变换器,LCD数字电路便直接显示出被测粮食含水量的百分数。
操作方法:
1. 开机:将开关拨到“开”的位置,仪器便显示出一定的数字。
2. 校正方法:取含水量接近标准值的粮食样品,用105℃烘干法先测试出被测品种粮食的水份含量,再用SC-5F水测仪的插入该粮食,并调节“校正”旋钮使数字与烘干法测出的水份含量读数值一致,然后倒去粮食,此时该仪器所显示的。
