Earth Ground Tester (Model 1621)
Manufacturer: Fluke
 
Price: $1,077.00 (USD)
Stock Status: 4 to 5 weeks
Earth Ground Tester for resistance measurement

The Fluke 1621 is an easy-to-use earth ground tester. For ground resistance testing, the 1621 is the first line of defense in detecting reliable ground connections. The unit features basic ground testing methods including 3-pole Fall-of-Potential as well as 2-pole ground resistance tests. Its convenient size, rugged holster, and large, clear LCD display make it an ideal field earth ground tester, for most electrical grounding work environments. With a simple user interface and intuitive functionality, the Fluke 1621 is a handy grounding tool for electrical contractors, utility test engineers, and earth ground specialists.


Features


  • 3-pole Fall-of-Potential earth testing for basic measurements

  • 2-pole resistance measurements for added versatility

  • Easily capture values with single-button operation

  • Ensure accurate measurements with automatic ‘noise’ voltage detection

  • Hazardous voltage warning offers increased user protection

  • Clearly read and record data with a large, backlit display

  • Rugged holster and design for tough work environments

  • Portable size allows for easy transportation

  • Instantly be alerted to measurements outside of your set limit, when you use the adjustable limit setting

  • 600 V Cat II

    Note:
    [1]If the tester is not going to be used, or is being stored for a long period, remove the battery and store separately from the tester to avoid damage from battery leakage.
    Note:
    [2]The four temperature ranges for the tester exists to satisfy European Standards requirements; the instrument can be used over the full working temperature range by using the temperature coefficient to calculate accuracy at the ambient temperature of use.
