Teach Engineering: Simple Coulter Counter
Students build and use a very basic Coulter electric sensing zone particle counter to count an unknown number of particles in a sample of "paint" to determine if enough particles per ml of paint exist to meet a quality standard. In a lab...

Teach Engineering: Particle Sensing: The Coulter Counter
Students are presented with a short activity on the Coulter principle, an electronic method to detect microscopic particles and determine their concentration in fluid. Depending on the focus of study, students can investigate the...
