Pressure Comparators
AMETEK Sensors, Test & Calibration
Our high-pressure, hydraulic pressure comparators are portable, self-contained, hydraulic pressure generators for calibrating pressure gauges, transmitters, sensors, and safety valves. They are much faster than deadweight testers and most automated pressure controllers; and it’s so quick and easy to use, it’s ideal for calibrating those low cost gauges that are often overlooked for ISO9000 compliance. Each pump is available on its own, or in one of our complete ready-to-use pump systems.

Comparative Dissolution Tester
CD14 Comparative Dissolution Tester
The Teledyne LABS 14-vessel CD14 Comparative Dissolution Tester runs two methods simultaneously or independently—ideal for bioequivalence studies of generic vs. innovator drug formulations. The 14 stirring positions allow for 6+1 or 12+2 configurations for improved workload efficiency in R&D, formulations, QC, and stability-test labs. With digital temperature probes at 12 positions the CD14 comparative dissolution tester is able to test two different formulations with separate settings for every parameter under the same temperature conditions.

Potential Transformers
Osborne Potential Transformers (PT’s) are used to reduce higher system voltages to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when potential transformers are to be used for power measuring applications.
