HARDNESS TEST AMPOULES
HARDNESS TEST AMPOULES (PCN 0365016) are a highly sensitive, safe, and easy-to-use method for the detection of low levels (0.5 ppm or less) of calcium and magnesium ions in water. The AMPOULES contain precisely measured reagents that are fully contained in vacuum-sealed glass which prevents contamination. Measurement errors are minimized because the precise sample size is drawn into the vacuum-sealed AMPOULE where it mixes with the premeasured reagents.
Calcium and magnesium ions are referenced together as “total hardness” and the concentration is expressed as <0.5 or >0.5 parts per million (ppm) as calcium carbonate.
