General Guidelines
- Ensure that the test tube is clean before use.
Clean the tube directly after use.
Take the volume of the water sample as precisely as possible.
Keep the dripping bottle perfectly vertical during dropping.
Take care that no air bubbles are included in the drops.
Test procedure:
-
Take a water sample of 5 ml.
-
Add 5 drops of KH-1 test fluid and mix.
The sample should turn lightblue; when it turns yellow, the KH of the water is lower than 1°DH. -
Mount the plastic tip onto the 1 ml syringe and fill the syringe with KH-2 test fluid. Above the fluid an air bubble will appear, this is normal. The air ompensates for the volume in the tip.
-
Add the fluid slowly until the sample colours yellow.
-
Multiply the amount of KH-2 test fluid in millilitre what was needed to let the colour convert from blue to yellow by 20 to calculate the KH in ˚DH. Or use the chart in this manual.
