Test 3in1

INSTRUCTIONS FOR USE
1. Remove the testing slip from the airtight packaging.
2. Immerse the slip into the tested water for 1–2 seconds so that all the zones get soaked.
3. Establishment of KH and GH values: After taking the slip out of water, put it immediately to the colour scale on the reverse side of the box and read the value by comparing the corresponding coloured zone on the slip with the colour on the scale.
4. Establishment of pH value: After taking the slip out of water, wait for 1 minute before you put it to the colour scale on the reverse side of the box and read the value by comparing the coloured pH zone on the slip with the colour on the scale.

General recommendations:
Keep the testing slips in a dry place.
Keep the testing slips in their original packaging.
Do not touch the inside of the box with wet hands.

Carbonate hardness and total hardness in the table are specified using German hardness grades (KH, GH). In order to obtain ppm units, multiply the values in German grades by 17.8.
