Basic Info.
Product Description
Manufacturer, exporters and suppliers of concrete resistivity tester
detection method:
adopt wenner sensor array (50 mm of spacing) to test concrete resistivity
test indicator: concrete resistivity
product model: nj-4000
product application:
concrete resistivity tester is also called potential detector (corrosion analyzer).the corrosion of reinforcement in concrete is an electrochemical process. it generates electricity to cause metal dissociated. if the resistance rate is lower, the corrosion current through the concrete will be easier, the corrosion possibility will be greater. so, to test the resistivity of the concrete can effectively evaluate its corrosion resistance and evaluate the existing corrosion degree.
product feature:
 sponge plug type sensor to ensure good electrical contact;
 128 * 128 large lcd screen display directly;
 rechargeable lithium battery guarantees long time work;
 keep test data function, continuously record, safe and reliable
 with micro-printer for printing directly
 multifunctional pc will be easy to data storage and processing
 portable waterproof instrument box will be easy to carry;
test object: reinforced concrete
detection principle:
adopt wenner sensor array (50mm of spacing) to test concrete resistivity, the resistivity unit will be kΩ•cm).according to the different range of test results, to evaluate its corrosion resistance.
