JapaneseMcOHM EL3i
The McOHM-EL3i is a cost-effective instrument that can be applied to both electrical sounding and well logging (resistivity, temperature & caliper). A color 10.1 inch LCD tablet, a large-capacity transmitter circuit part and a high-performance potential measurement part are all stored in one compact case, giving this instrument superior operability and portability.
It is equipped with a powerful transmitter (400V, 120mA), a preamplifier with a high input resistance of 10MΩ and a 24bit A/D converter, and a high-performance receiver is mounted to enable measurements with a resolution of 0.001mV. Also, its data are in comma-separated value (CSV) format that can be edited on a PC easily.
