Elspec is a leading global provider of advanced power quality analyzers, power quality solutions and power monitoring software. We focus on developing technology that shifts the power quality market to the next level. With over 45 years of experience, we develop tailor-made power quality solutions along with state of the art power quality analyzers.
The Pure BlackBox, an advanced handheld power quality analyzer equipped with PQZIP Technology, is an easy to use plug and play device that continuously records all power quality parameters without thresholds settings or recording configuration. The device is available in 2 versions: Single Phase, 3-Phase.
Continuous waveform recording
The Pure BlackBox continuously records voltage and current waveform sampled at a rate of 256 Sample/Cycle at 50/60Hz . Which provides information at a very high resolution, enabling to detect and analyze the slightest change without the need to set up triggers or thresholds.

More than 5,000 power quality parameters such as RMS, THD, powers, power factor, unbalance and harmonics are logged continuously for more than a year at half cycle, 10/12 Cycles, 150/180 Cycles, and 2 hours resolution.


The Pure BlackBox records and stores 128 harmonics components at 50Hz resolution and 512 inter-harmonics components at 5Hz resolution for both voltage and current.
The PureBB is designed to detect any event occurring on your system. The PureBB analyzer is capable of recording waveform signals continuously. The event configuration doesn’t trigger the recording but rather stores summary logs including start and end time, duration, severity and magnitude of the event. All events can be displayed in a tabular or scatter charts as CBEME/ITIC.
