Megger DET4TD2-4-Terminal Ground Resistance And Soil Resistivity Tester

The Megger DET4TD2 is a highly advanced earth loop tester designed for robust and efficient 2, 3, and 4-point testing with a versatile 25V or 50V output. This upgraded unit from Megger is equipped with features that make it suitable for both indoor and outdoor use, boasting an IP54 rating which ensures protection against dust ingress and water jets.

Key Features and Capabilities of the Megger DET4TD2:

• Dual Voltage Testing Capability: The DET4TD2 allows for easy switching between 25V and 50V test modes. This flexibility is essential for adhering to various testing standards and conditions, enhancing its utility across different environments and applications.
• User-Friendly Interface: The device features a large rotary dial and a single test button that simplifies the selection and initiation of tests. This design ensures that operations are straightforward and can be performed efficiently in field conditions.
• Advanced Spike Checking: An innovative feature of the DET4TD2 is its ability to automatically analyze and report on the connection status and integrity of P and C spikes. The results are clearly displayed on the built-in LCD screen, providing immediate feedback and diagnostic capabilities.
• Built-in Voltmeter: With its integrated voltmeter, the DET4TD2 is capable of accurately detecting ground voltage. It offers a wide measurement range, able to measure earth voltages up to 100V and resistance from 0.01 ohms to 20k ohms. The resistance measurement accuracy is impressive at 2% ± 3 digits, ensuring reliable and precise readings.
• Battery Powered for Enhanced Portability: Unlike its sister model, the DET4TR2, which is rechargeable, the DET4TD2 operates on eight AA batteries. This non-rechargeable feature emphasizes its readiness for use in locations where charging facilities might be limited.
• Safety and Compliance: The DET4TD2 meets rigorous safety standards, including IEC61010-1 100V CAT IV between terminal pairs, ensuring safety during operation even under the most demanding conditions. It also conforms to KEMA K85B and EN61557 standards, which cover electrical safety in low voltage distribution systems up to 1000V AC and 1500V DC.

The Megger DET4TD2 is an essential tool for professionals who require a reliable, accurate, and easy-to-use earth testing solution. Its robust construction combined with advanced testing capabilities makes it an ideal choice for ensuring the integrity and safety of electrical installations. Whether used in utility, construction, or industrial applications, the DET4TD2 provides the performance and durability needed to meet the challenges of modern electrical safety testing.
