SK-4000混凝土电阻率仪

检测方法:利用Wenner阵列传感器(50mm的间距)测试混凝土电阻率
测试指标:混凝土电阻率

产品用途
混凝土电阻率测定仪也叫电位检测仪(锈蚀分析仪),混凝土中钢筋的腐蚀是一个电化学过程,它产生电流使金属离解,电阻率越低,腐蚀电流流过混凝土就越容易,腐蚀的可能性就越大,因此测量混凝土的电阻率可以有效评价其抗腐蚀能力和评估现有钢筋的腐蚀程度。

产品特点
1. 海绵塞式传感器确保良好电接触的;
2.128*128大液晶屏幕直显;
3.可充电锂电池保证长时间工作;
4.测试数据保持功能,连续记录、安全可靠;
5.附微型打印机直接打印;
6.多功能上位机易于数据保存与整理;
7.便携式防水仪器箱易于携带;
测试对象:钢筋混凝土。
检测原理
利用Wenner阵列传感器(50mm的间距)测试混凝土电阻率,所测的电阻率以kΩ•cm为单位的。根据测试结果的不同范围可评价其抗腐蚀能力。
