HT Italia GEO 416 Earth Resistance and Ground Resistivity Tester with Data Download

HT_Italia_Ca

GEO416 has been developed to measure earth resistance with 2 wires, 3 wires and 4 wires by voltammetric method and ground resistivity. These values are extremely important while designing earth systems.

The 2-wire method, by taking advantage of appropriate external masses as a reference (metal surfaces, tubes, neutral conductor, etc.), is particularly useful in private environments where, because of logistic problems, it is not possible to use the 3-wire method. The device allows carrying out measurements with a wide measuring range (up to 50kOhm) with an efficient internal compensation of the disturbance effects found on the installations. GEO416 is provided with an internal memory for saving measurements and with an optical/USB interface for transferring measured data onto the PC

Description
Reviews (0)

The HT Italia GEO 416 Earth Resistance and Ground Resistivity Tester designed to performing Earth Resistance measurements with 3-pole standards method typically in industrial electrical installations environments which consists of single probes and more or less wide earth networks. This meter can perform also 2-pole measure (where auxiliary metal parts are available) extremely important in civil environments where 3-pole method application is not possible for logistical reasons.

The HT Italia GEO 416 performs tests with a high measurement range (up to 50kOhm) with a test current at high frequency in order to consider and eliminate noise voltages disturb on installation. Earth Resistivity test measure with 4-wire method it’s also very useful on preliminary calculation of earth installation dimension. A contextual help selectable by user it’s available on meter for each functions. The model can save each test result inside memory and can transfer saved dates to PC through optical / USB interface with dedicated Windows software.
