Instran Hardness (Low Concentration Range) Concentration Meter
By using a photometer, we achieve high measurement accuracy.
Calcium and magnesium form complexes with cresol red. When a buffer is added to adjust the pH to about 9.6, a characteristic purple complex is produced. When measuring only calcium, magnesium can be complexed to eliminate interference.
