With the SpaBalancer Total Hardness Test Kit you can determine the hardness of your spa water.
Application:
1. Fill 5ml of water into the measuring cup.
2. Now add the measuring liquid drop by drop to the water and . Count each drop you add.
3. Shake the liquid after each drop so that the water and the measuring liquid mix well.
4. The water now turns red.
5. As soon as the water changes color from red to green, you have determined the water hardness: Number of drops = water hardness in degrees of German hardness / 10 drops = 10 degrees of German hardness.
Conversion of water hardness:
fH°: degrees of French hardness / e°: degrees of lime / dH°: degrees of German hardness
dH° | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 |
fH° | 9 | 18 | 27 | 36 | 45 | 53 | 62 | 71 | 80 | 89 |
e° | 6 | 13 | 19 | 26 | 31 | 38 | 44 | 50 | 56 | 63 |
