AEMC 8335 (2136.20) Three-Phase Power Quality Analyzer

DISCONTINUED ITEM- Replacement Model: AEMC 8336 (2136.30) Three-Phase Power Quality Analyzer

The PowerPad^® Model 8335 is a three-phase power quality analyzer that is easy-to-use, compact and shock-resistant. It is intended for technicians and engineers to measure and carry out diagnostic work and power quality work on one, two or three phase low voltage networks.

The PowerPad^® 2GB of memory is conveniently partitioned to let you store four different types of data, synchronized or independent of each other. You can store up to 50 screen snapshots, up to 300 captured transients that contain four cycles for each active input, and 10,000 alarm events from up to 40 different parameters. You can also record trend data for days, weeks or even months.
