Detection principle:
NJAL-H rapid concrete alkali tester adopts ion selective electrode method (ISE method) rapidly to test the alkali content of the water-soluble matter, such as concrete, gravel, and additive.
The concrete or other samples should be pretreated before usage. Put the two prior activated and calibrated electrode into the mixture according to the instructions, one of the electrode tests the sodium ion content, the other one tests the potassium ion content. The instrument can turn the tested voltage data (mv) into Na2O and K2O content (%) through the calibration curve. After filling the result to the host calculation formula ,it will automatically get the Na2O percentage (%) of the concrete alkali content. After the electrode activation, each experiment process will need only 10 minutes.
