Generally used in Geology to analyze the soil type before creating structures and foundations in it. This equipment generates an output voltage of up to 1000 Vdc with an input powered by a 12 Vdc battery, which allows work in the field without needing another power supply.
It is composed by four modules connected in series that provide 250 Vdc each. According to the number of modules selected, the output will have a corresponding voltage (250, 500, 750, 1000), which can also be adjusted to intermediate values using a Variac.
Equipment composed by:
- DC / DC converter from 12 to 1000V
- Millivoltmeter
