If you google the term 'breakdown voltage meter', you will find that although there is equipment that can measure this voltage, you have to pay hundreds to over a thousand euros for it. If you only occasionally feel the need to measure the breakdown voltage of a component, this small and inexpensive device offers a useful alternative to its much more expensive counterparts. That there is such a large ripple on the output voltage of 600 V may not be as it should be, but that probably has very little impact on measuring the breakdown voltage of a component.

Very nice and handy device to determine the breakdown voltage (BRV) of semiconductors, VDRs and such stuff. It comes without any manual. but use is quite straightforward: only connect the seiconductor union to be tested in reverse polarity, minimun current & voltage, and start increasing voltage slowly until display numbers stops increasing with voltage knob rotation. In the photo you can see a double diode with a BRV of 190 V. The other diode aside is a high voltage special one for microwave ovens with a BRV of 5 Kv, so it's out of range for measurement (voltage in mine reaches a maximun of 2720 V). Anyhow, a recommendable devide to have in the lab. Simple, but effective and a nice to have item. It came fully charged, so I was able to test it inmediately. Take advantage while flash sale lasts as it is at $21.99; more than 50% discount!
