Our Dyne Testing Pens are the valve tip applicator type and not the "Felt Tip Pen"
type. The Valve Tip Applicator principle is simple: Keep the testing part of the pen
away from the fluid storage part of the pen, to eliminate wicking from the substrate.
Pressing the pen tip firmly down, opens the valve and fresh fluid floods the tip; thus
flushing it clean, this allows the tester to lightly pass over the sample to accurately
determine the Dyne level. The disposable pens have a fluid capacity of 15ml and
are available in 1 Dyne (mN/m) increments from 34 to 70 mN/m.
