About DET3TC Three-terminal earth/ground resistance tester

2 and 3 point testing
ART (Attached Rod Technique) testing capability
Selectable 25 V or 50 V output
Warning indicators prevent test failure
IP54 rated
Complete with leads, stakes, and rugged carry case
Simple one-button operation
Calibration test certificate included
Optional earth testing kit (ETK) available

The DET3TC is capable of testing on-site grounds without disconnecting the utility connection. The complete kit gives you everything you need to start testing and consists of the instrument, test leads, stakes, batteries, and calibration certificate delivered in a tough polypropylene carry case.

The DET3TC is easy to use, with a large selector switch that enables you to change between two-pole or three-pole testing, and can be operated easily with gloved hands. What's more, the design makes the fitting of shorting links for two-pole testing a thing of the past.

The earth/ground rod tester is rated to IP54, making it a hardy outdoor instrument. Using the optional clamp around the earth/ground rod connection allows the testing of the rod without the need for disconnection, leaving the earthing system intact during testing (ART). A large, clear, easy-to-read LCD display and thumb-sized test button also makes the instrument particularly suited outdoor conditions.

Advanced Safety and Durability

The DET3TC tester is engineered for high reliability, incorporating overvoltage protection on all terminals and a voltage warning indicator to alert users of hazardous voltages during testing. Its rugged ABS casing offers excellent impact resistance, and IP54-rated dust and water protection ensures dependable operation in challenging environments. Designed to meet IEC61010 CAT IV 100V safety standards, this device delivers peace of mind during demanding fieldwork.

Versatile Field Applications

Tailored for measuring earth and ground resistance in a variety of electrical installations, the DET3TC is perfect for utilities, construction, and maintenance professionals. Its ability to use test leads up to 30 meters and operate across a wide temperature range, from -15C to +55C, makes it adaptable to both indoor and outdoor environments. The inclusion of a carry pouch and lightweight, compact design enhances portability and convenience on-site.
