RENT ARBITER 933A Portable Power Sentinel Power Quality Meter (Call for Availability)

The Arbiter Systems Model 933A Portable Power Sentinel is the most accurate and most affordable portable power quality meter in the industry. The proprietary EnergyDSA Digital Signal Analysis algorithms allow the user to measure or record harmonics, flicker (per IEC 61 000-4-1 5, P_ST and Instantaneous), K-factor, and interruptions.  The high accuracy, portability and data logging capabilities make the Portable Power Sentinel the perfect field analyzer for the power quality engineer. Weighing less than 5.8 kg (1 2.8 lbs), the Portable Power Sentinel is a power quality monitor, a data and event logger, a system monitor, and a revenue meter designed to accompany you wherever you go.

Primarily designed for the power engineer, the Arbiter 933A Portable Power Sentinel measures and records harmonics, flicker, K-factor, and interruptions. In addition to these measurements, the Portable Power Sentinel has the ability to measure system time, phase, frequency, and phasors. The DSP memory is primarily for waveform storage with data for all channels continuously stored at approximately 1 70 samples per cycle, a fixed pre-fault window of 0.5 seconds, and a maximum of about 1,000 seconds (17 minutes) of data storage. Available options include remote GPS receiver synchronization for 1 µs timing accuracy allowing for increased revenue accuracy, optically isolated event inputs, flexible CT inputs, direct current inputs, and programmable KYZ output contacts.
