The 2SGA-1000 represents the world’s thinnest Natural Gamma (GR) probe and is capable of operating even inside the narrowest boreholes.

With this probe the sampler is lowered to the desired depth and through the acquisition interface it is possible to open the chamber for on-site sampling.

The HFP-2293 Heat Pulse Flowmeter is a special borehole water flow velocity meter designed for measuring particularly low flows.

Radioactive source log. The QL40-NEU Neutron spacecraft uses a He-3 thermal neutron detector sensor.

The QL40-OCEAN Idronaut Ocean Seven 303 is a multi-parameter probe produced in Italy, ideal for continuous analysis and environmental monitoring activities in the borehole.

The QL40-DEV probe is used to evaluate the deviation of holes from the vertical.

The QL40-DLL3 Dual Laterolog probe allows for focused resistivity measurements on dual-spaced arrays with two different exploration depths.

The QL40-GR-CCL probe allows for “natural gamma ray” (GR) and “casing collar locator” (CCL) measurements.

Log for measuring the natural radioactivity of the soil which allows the identification of individual radioisotopes present in the soil.

The QL40-DEN probe allows you to perform SSD (short-spaced density), LSD (long-spaced density), Compensated density (dual density) and Caliper density measurements.

The QL40-MGS probe for magnetic susceptibility measurements finds applications in the mining, geotechnical and lithostratigraphic fields (for example in volcanic areas).

It allows the measurement of the apparent conductivity of the soil in mS/m (inverse of the resistivity) using the principle of electromagnetic induction.

Log for measuring the velocity of P, S waves (in rock).

Log for measuring the flow velocity of the fluid inside the hole by measuring the rotational speed of a propeller.

Second-generation optical probe, based on a completely new sensor (high-resolution CMOS) and electronics.

Second-generation tool based on the emission of an ultrasonic acoustic pulse by generating and recording the amplitude and arrival times of the signal.

Log for the continuous measurement of electrical conductivity (µS/cm normalized to 25°C) and temperature (°C) of the fluid present in the hole.

3-Arm Caliper (QL40-CAL) Log that measures the borehole diameter, which allows for the identification of more or less fractured and/or permeable areas.

Log for measuring subsurface electrical resistivity (ohm*m) using the ABMN acquisition scheme at 4 different spacings (8, 16, 32, and 64”)

This log features extreme precision and ease of use, suitable for use in both cased and uncased boreholes.
