NJAL-H

Portable Rapid concrete Alkali Content Tester tests the alkali content to prevent the alkali aggregate reaction in concrete construction.
With Ion Selective Electrode Method(ISE), the composite Potassium Ion Electrode and composite Sodium Ions Electrode rapidly test the Alkali content (%) under room temperature in the concrete: Fresh concrete, Wet concrete, Harden concrete, Power sample and Raw material: Cement, chemical additive, admixture.
