ABSTRACT:
A surface energy meter (10) includes a probe (18) having two spaced apart electrodes (38 and 40) with a centrally located fluid dispensing head (36). When a fluid of known surface tension is dispensed onto a material (22) having unknown surface energy, the surface energy is determined by the volume of a fluid drop (42) which bridges between electrodes (38 and 40). The volume of the fluid drop (42) is closely regulated using a stepper motor (24) and by tracking the number of steps and volume dispensed per step required for the fluid drop (42) to expand to a point where the electrodes (38 and 40) are bridged. When a fluid of unknown surface tension is to be tested, materials having known surface energies are used.
