Lyphan rolls provide a quick overview measurement, when you require a precise measurement for liquids where you already know which general area of the pH scale they fall in.
The Lyphan rolls are available as follows: Strips with two zones adjacent to each other (R3969, R4979, R6999), strips with three adjacent zones (R111) or strips with four adjacent indicator zones, (R014). These strips guarantee very high accuracy and precise readability.
Lyphan rolls come in a sealed plastic box with rotating roll of 6m test paper. This roll of 6 meters, allows approximately 150 measurements to be made.

Instructions for use pH indicator paper (rolls):
To use the indicator roll, turn the top of the container counter-clockwise until you have the desired length of indicator paper. Tear off the strip, and dip it for 1 to 2 seconds into the solution you wish to test.
Then compare the wet strip to the color scale on the box and assign the corresponding pH Value.
In the case of the roll product R014, the two outer bands that measure pH from 8 to 11have the same color (blue) and then at the point where the pH level is 11 and greater, only the first outer blue band changes its colour.
The comparison scale for this measurement, pH levels from 11 to 14, are on the back of the container.
