Clarke-Hess 2600 Broadband Phase Meter

The Clarke-Hess 2600 is a versatile Phase Angle Voltmeter (PAV) designed for precise measurements in electrical engineering applications, including Synchro/Resolver and LVDT/RVDT testing. It has advanced DSP technology for enhanced performance and user-friendliness, replacing the previous Model 2500A. The instrument's design prioritizes ease of use with "at the touch of a button" classic measurements, functioning more as a dedicated instrument than a complex computer. This makes it suitable for laboratories, industrial environments, and research facilities where reliable and accurate electrical measurements are critical.
