Dosatest strips incorporate a colour scale and are ideal for determining pH values for coloured solutions.

• Reliable even in coloured samples
• Versatile and economic
• Handle remains dry and clean whatever the sample

Due to the scale in the strip, any sample colour will have the same effect on the reference colour as on the reactive strip ensuring accurate readings even in coloured samples.

Invisible hydrophobic barrier above the top colour field on the strip stops capillary action of the test solution and prevents contact with the user.
