PRO ERT-1602 Earth Resistance and Soil Resistivity Tester

48,600.00 including GST @18%


Precision 4-wire, 3-wire and simple 2-wire measurement for Earth Resistance, Soil Resistivity, Earth Voltage and AC Voltage. Complete kit in hard carrying case.



The Pro ERT-1602 features precision 4-wire, 3-wire and simple 2-wire measurement methods to measure Earth Resistance, Soil Resistivity, Earth Voltage and AC Voltage. Unlike other Earth Testers, you do not need to calculate Soil Resistivity as this instrument gives you the measurement directly.

This Earth Resistance Soil Resistivity Tester comprises of host machine, monitoring software, test wires, auxiliary ground rod and communication cable.

It can store up to 300 sets of data simultaneously, through the monitoring software to document and analyse historical data.

It also offers online real-time monitoring functions, dynamic display, alarm indication with historical data reading, accessing, saving, reporting, printing and other functions.
