Rapid Measuring Instrument for Alkali Content of Concrete

Model: HC-RAT

I. Overview

Rapid determination instrument for alkali content in concreteThe detection principle is to use the ion selective electrode (ISE) method to quickly determine the alkali content of samples such as concrete, sand and gravel, and additives. Pre treat concrete or other samples during use. Immerse two pre activated and calibrated electrodes into a mixed solution as instructed, with one measuring sodium ion content and the other measuring potassium ion content. The instrument can convert the measured voltage data (mv) into Na2O and K2O content (%) using calibration curves, and automatically obtain the concrete alkali percentage Na2O (%) by inputting the results into the calculation formula in the host computer.
