Two probe-type capacitance meters
Journal of the British Institution of Radio Engineers, 1954Two types of instrument are described, suitable for the measurement of wiring and component earth capacitances in electronic apparatus. The instruments have a range of 50 pF and consist of a probe and an indicator unit. In the first instrument a substitution method is used.

A Capacitance Meter for Bilayer Membrane Studies
Review of Scientific Instruments, 1972A meter which features direct readout of the capacitance of artificial lipid bilayer membranes is described. It is basically an ac ohmmeter that has been designed to minimize the commonly encountered series (solution) and input resistance errors. An accuracy of about 3% can be achieved for typical membrane capacitances of 10−3−10−1 μF.
