Megger DET4TD2 Earth Tester

Megger DET4TD2 Earth Tester

SKU: 1001

Megger's DET4TD2 serves as an earth loop tester, capable of conducting 2, 3, and 4 point testing while offering the choice between 25V and 50V output levels. Its versatility extends to both indoor and outdoor applications, facilitated by its IP54 rating, which safeguards against dust and water jets. Effortless to establish connections, this instrument simplifies testing through its sizeable rotary dial and prominent test button. Notably, a dedicated switch on the front permits seamless transition between 25V and 50V modes.

This earth tester also boasts an automatic assessment and display of connected P and C spikes, showcasing outcomes on its integrated LCD screen. Moreover, the DET4TD2 doubles as a ground voltage measuring tool, featuring an embedded voltmeter. Its capabilities span measurements of earth voltages reaching 100V and resistance evaluations spanning from 0.01Ω to 20kΩ, accompanied by a precision of 2%±3 digits.

This product aligns with the stipulations of IEC61010-1 at 100V CAT IV across terminal pairs, given the use of a compatible leadset. Additionally, the DET4TD2 adheres to the standards of KEMA K85B and EN61557, which pertain to electrical safety within low voltage distribution systems up to 1000V AC and 1500V DC, encompassing equipment designed for testing, measuring, or monitoring protective measures.
