Fluke 1621 Earth Tester

Fluke 1621 ground resistance meter for portable use

The Fluke 1621 ground resistance meter offers basic methods for measuring ground resistance, such as the three-wire potential drop method and the two-wire ground resistance method. The ground resistance meter has a compact design, its robust case and its wide and clear LCD screen make it the ideal instrument for checking ground resistance for most work environments. The handling of the ground resistance meter makes it a practical tool for electricians, installation engineers, and ground resistance measurement specialists.

- 3-wire potential drop method for basic measurements 

- Ground resistance measurements with 2 wires for greater versatility 

- Easy value capture with just a button press 

- Guaranteed precision measurements thanks to automatic detection of electrical noise 

- The warning function for dangerous voltages provides added safety for the user 

- Large backlit display that allows easy reading and recording of data 

- Robust design and durable casing for the most adverse working environments 

- Its manageable size allows for easy transport 

- Thanks to the ability to adjust the working limits, the equipment alerts you of the measurements that

  they are outside of those limits 600 V Cat II
