Abstract
A simple densitometer for use in sound processing laboratories is described, employing the Weston photronic cell and a 50-cp., 12-v. lamp. The cell current is measured by a microammeter, suitably damped. The instrument retains its calibration well, densities can be measured within 0.005, and readings are consistently duplicated.
