product description
In order to avoid premature corrosion of the steel, the chloride ion content in the concrete raw material is quite strict, and the relevant specification in our country specifically requires the concrete to be mixed with the sand, aggregate, cement, admixture, Concrete raw materials, it is necessary to test the content of chloride ions, from the fundamental to avoid excessive chloride ions into the concrete in the structure of chloride ion content of the test, for the assessment of structural safety play a significant role, The old structure of the transformation and repair provide a reference value.
The instrument follows the "concrete structure durability design specification" GB / T 50476-2008, "sea sand concrete application technical specification" JGJ206-2010, "water transport engineering concrete test procedure" JTJ 270-98 and other related standards manufacturing, the use of ion-selective electrode (Ion Selective Electrode, ISE method), through the provision of professional software and chemical anti-jamming reagents at room temperature rapid determination of concrete, sand, cement, mixed water and other inorganic materials, water-soluble chloride ion content, so as to achieve control of concrete The purpose of the early corrosion of the steel. The instrument light weight, compact body, easy to carry, suitable for on-site testing. Chloride ion concentration measurement range 10-5~ 10-1 M (mol • L-1) or 0.0001% to 30.00%.
