Arbiter 931A Power Analyzer

The Arbiter 931A Power Analyzer sets a new standard in power testing technology. Designed for professionals seeking precision and reliability, this advanced analyzer offers a remarkable basic accuracy of 0.05% of reading and 0.05° phase accuracy, ensuring that you capture the essence of power quality in your measurements.

Equipped with Digital Signal Analysis (PowerDSA™), the Arbiter 931A measures essential parameters, including true-rms voltage and current, frequency, and phase angle. It also accurately calculates key power quantities such as:

• Watts (W)
• Watthours (Wh)
• Volt-amperes (VA)
• Volt-ampere hours (VAh)
• Volt-amperes reactive (VAR)
• Volt-amperes reactive hours (VARh)
• Power factor (PF)

All of these parameters achieve a fundamental accuracy of 0.11%, making the Arbiter 931A a trusted tool for comprehensive power analysis.

The device boasts a high-contrast 240x64 graphic display that allows you to view harmonic measurements and graphical results intuitively. The two channels are normalized to Channel 1's fundamental phase, enabling detailed visual analysis between current waveform distortions and voltage phases.
