Cary 401. The Cary 401 Vibrating Reed Electrometer, the most accurate in the world, detects currents of 10"17 ampere, charges as small as 5 χ 10" 16 coulomb, and potentials down to 2 χ 10 - 5 volt from high impedance sources. Its standard features include solid state circuitry, multiple resistor input switching, remote input shorting, 1-second critically damped response time, and measurement of potentials from grounded sources. Modified versions offer critically damped response times of 0.5 and 2 seconds, and range changing can be computer controlled. So, if your application is in mass spectrometry, radioactivity, physical measurement or biomedical research, the Cary 401 can tackle just about any problem you've got to solve. For more information on the top vibrating reed electrometer commercially available, write Cary Instruments, a Varian subsidiary, 2724 S. Peck Road, Monrovia, California 91016. Ask for data file P203-22.
Still the most sensitive, stable, and reliable electrometer on this planet.
