KYORITSU 4106 EARTH RESISTANCE & RESISTIVITY TESTER

Kyoritsu 4106 Earth Resistance & Resistivity Tester

The Kyoritsu 4106 Earth Resistance & Resistivity Tester is a high-performance instrument designed for engineers, contractors, and electrical professionals who require accurate, reliable, and versatile earth testing. With six measurement ranges covering 0.001 Ω to 200 kΩ, it is suitable for a wide range of applications, making it a flexible solution for both field and laboratory work.

In addition, this tester features automatic earth resistivity (ρ) calculation using the Wenner method, eliminating the need for manual computations and saving valuable time during measurements. Moreover, the advanced FFT-based noise filtering ensures stable readings even in electrically noisy environments, while the automatic/manual selection of four test current frequencies provides adaptability for different testing scenarios.

Furthermore, the Kyoritsu 4106 is built for durability with IP54-rated rugged construction, ensuring reliable performance in challenging field conditions. Additionally, its generous memory storage for up to 800 results allows for easy on-screen recall, and data can be conveniently transferred to a PC via an optional USB adapter and specialized software.

As a result, the Kyoritsu 4106 Earth Resistance & Resistivity Tester combines precision, advanced functionality, and robust design, making it an indispensable tool for professionals who demand accuracy and dependability in earth testing.
