Syscal Pro
The Syscal Pro is an all-in-one multinode resistivity and induce polarization sounding and profiling system for environmental and engineering geophysical studies. The Syscal Pro gathers a 10 channels receiver and a 250 W internal transmitter which make it the more powerful system of the Syscal range. Compact, easy-to-use and field proof, the Syscal Pro measures both resistivity and chargeability. It is ideal for environmental and civil engineering applications such as depth-to-rock determination, weathered bedrock mapping. With a maximal output voltage of 2000Vpp, the Syscal Pro is very adapted to detect deep fault in fractured aquifers or to characterize the depths and thickness of the groundwater aquifers.

Earth Tester
TAURUS PRECIOHM ET
The TAURUS PRECIOHM ET is one of the specially designed products by TAURUS to measure earth resistivity and earth resistance in a power station. These tests are performed based on 4 point (Wenner) and 3 point (fall of potential) methods respectively. All electrical equipment in the substation and power stations are electrically connected to station earth mat with earth electrodes. The earth electrode ensures that in the event over voltage on the system due to system fault or lighting discharges etc., the parts of the equipment which are normally ”dead” as far as voltages are concerned; do not attain dangerously high potentials. An earth electrode will only be effective so long it has a low resistance to the earth and can carry large currents without deteriorating. Thus the resistance of earth electrode should be low to give good protection and it must be continuously measured and monitored in all the substations and power stations.

Resistivity Meters
Periodic compliance checks of ESD work surfaces are super important. Monitors only verify the ground plane, or path to ground. The surface itself can wear down, become dirty, or if you use low quality mat—just not hold up. A handheld Surface Meter is great for running monthly, or prescriptive compliance verification of your ESD surfaces.

Geo-electrical Resistivity Logging Exploration System
Resistivity logging measures the subsurface electrical apparent resistivity, which is the ability to impede the flow of electric current. This helps to differentiate between formations filled with salty waters (good conductors of electricity) and those filled with hydrocarbons (poor conductors of electricity). Resistivity and porosity measurements are used to calculate water saturation. Resistivity is expressed in ohms or ohms\meter, and is frequently charted on a logarithm scale versus depth because of the large range of resistivity. The distance from the borehole penetrated by the current varies with the tool, from a few centimeters to one meter.
