HT Instruments GEO 416 Earth Ground Resistance and Earth Resistivity Tester with Internal Memory

Description

The HT Instruments GEO 416 is an earth ground resistance and resistivity tester for electrical installations. It measures earth resistance using two, three, or four wires and is capable of testing both industrial and civil environments. The device is part of HT Instruments' "family 400" line of products, which was introduced in 2007.

Key Features

• Measurement capabilities: Measures earth resistance using the 2-, 3-, and 4-wire voltammetric methods. It can also test ground resistivity.
• Wide measuring range: Capable of measuring resistance up to 50kΩ.
• Interference compensation: Uses a high-frequency test current to help mitigate the effects of noise voltages on measurements.
• Internal memory: Stores measurement results for later retrieval.
• PC connectivity: Includes an optical/USB interface and dedicated Windows software (TOPVIEW) to transfer saved data to a PC.
• Cable calibration: Automatically calibrates the resistance of its test cables.
• On-screen help: The user can access contextual help for all functions directly on the backlit LCD display.
• Power and safety: The device runs on six AA batteries and has a CAT III surge protection rating of 240V, according to ValueTronics.
