SKCL-C型氯离子含量快速测定仪

检测方法:ISE法
执行标准
《水运工程混凝土试验规程》JTJ 270-98
《混凝土结构耐久性设计规范》GB/T 50476-2008
《海砂混凝土应用技术规范》JGJ206-2010
测试指标:氯离子浓度、质量百分比

产品介绍
氯离子是诱发钢筋锈蚀的重要因素,为了避免钢筋过早锈蚀,混凝土原材料中氯离子含量的控制相当严格。我国相关规范明确要求混凝土在选配砂子、骨料、水泥、外加剂、拌和水等混凝土原材料的时候,必须进行氯离子含量的测试,从根本上避免将过量氯离子带入混凝土中。结构混凝土中氯离子含量的测试,对于结构安全性的评估起到很大的作用,同时为旧结构的改造和修补提供极具参考价值的依据。
本仪器遵循《混凝土结构耐久性设计规范》GB/T 50476-2008、《海砂混凝土应用技术规范》JGJ206-2010、《水运工程混凝土试验规程》JTJ 270-98等相关标准制造,采用离子选择电极法(Ion Selective Electrode, ISE法),通过配备的专业软件及化学抗干扰试剂在室温下快速测定混凝土、砂石子、水泥、拌合水等无机材料的水溶性氯离子含量,从而达到防控混凝土钢筋发生过早腐蚀的目的。本仪器重量轻,机身小巧,便于用户携带,适合现场检测。氯离子浓度量测范围10-5~10-1 M(mol/L)或0.0001%~30.00%。

产品特点
1.可测定混凝土拌合物、硬质混凝土、砂石子、外加剂、水等材料的水溶性氯离子含量,直接输出以摩尔浓度和百分比为单位的结果;
2.内置标准公式,直接计算混凝土拌合物的氯离子含量
3.特有抗离子干扰剂,去除氰、氨等离子的氧化效应以及锰、铅等金属离子的络合效应
4.大屏幕液晶直显,即时打印,一键完成测试,使用操作简易
5.重量轻,机身小巧,便于用户携带,适合现场检测
6.可选配微型打印机,即使不通过电脑也可立时打印
7.独有自诊断功能,独创上位机分析软件
8.大容量数据存储,可存储100个测试数据,数据连续记录,安全可靠
测试对象:海砂、普通砂、新拌混凝土、硬质混凝土、水泥、石子、外加剂、混凝土拌合水及其他水溶性氯离子。
