DY4100

The Duoyi Dy4100 Digital Megohmmeter Earth Resistance Tester is an essential tool for measuring the electrical resistance of conductors and soil in various applications. This versatile device is designed to help you ensure the safety and efficiency of electrical systems and earth grounding.

The Megohmmeter features a large, clear LCD screen that displays the measurement results in real-time. The screen is backlit for easy reading in low-light conditions, and it shows the resistance value in ohms, as well as the test current and voltage levels. The instrument can measure resistance values ranging from 0 to 2000 ohms, making it suitable for a wide range of applications.

The Duoyi Dy4100 Digital Megohmmeter Earth Resistance Tester is powered by two AA batteries (not included) and is compact and portable, making it easy to carry in the field or bring to multiple job sites. The device is housed in a sturdy, water-resistant case that protects it from dust, moisture, and accidental drops.

The Megohmmeter operates using a two-pole probe with test leads. The probe can be connected to the ground and the conductive material or soil to be tested. The device applies a known alternating current (AC) to the material and measures the resulting voltage drop across the material. The resistance value is then calculated based on the applied current and voltage.

The instrument is equipped with overload protection and reverse polarity protection, ensuring the safety of both the user and the device during testing. It also features an automatic shut-off function to conserve battery life when not in use.

The Duoyi Dy4100 Digital Megohmmeter Earth Resistance Tester is an ideal tool for electricians, technicians, engineers, and anyone who needs to measure the electrical resistance of conductors or soil. It is used in various industries, including power generation, construction, telecommunications, and transportation, to ensure the safety, efficiency, and reliability of electrical systems and earth grounding.
