DUOTEST indicator papers pH 1,0 - 4,3

DUOTEST indicator papers pH 1,0 - 4,3 has two different indicator zones on one strip.
They are separated by a hydrophobic strip, that prevents the blending of the indicator colors and increases the mechanical stability. Explicit color differences gaurantee a safe assessment of intermediate values. Therefore increases the measurement accuracy.
With impregnated specific color indicators for defined pH scales.
Rapid and easy pH measurment, available in many diverse designs.
Handy plastic reel for example ensures long-term stability and protection against mandy external influences.
