Specifications of the I F G multi parameter probe (BMP-06)
Conductivity, Magnetic Susceptibility, Resistivity, Natural Gamma, Temperature.
The multi-parameter probe measures the parameters of inductive conductivity, magnetic susceptibility, galvanic resistivity, natural gamma and temperature. The sensors and the electronics circuits are contained within the probe of the size of 170 cm by 40 mm. All measurements are taken synchronously at a rate of 2 times per second. Including the gamma counts are integrated over a time period of 0.5 second with a maximum dead time of 30 ms or 6% of the accumulation time.
