AKTAKOM ATK-5307 is a compact (7.5 x 5.5 x 3.03 in only) digital ground tester which is designed to measure resistance of different objects not charged with electricity.

Among the main features:

• Measures grounding connection resistance within 0.01Ω… 4kΩ
• Ground potential measurement with 0.1V resolution
• Data hold, MAX / MIN function.
• Auto power off function (in 3 minutes).
• Measurement time: 2.5 times per sec.
• Wide range and high precision
• All ranges are selected with one switcher
• Overload protection system
• Solid plastic housing

The main specifications are shown in the below table:
