What's special about this grounding tester?

  • Measures the resistance of any existing earth conductor to help determine its suitability for grounding, ensuring that standards for electrical installations are met
  • Ideal for electrical workers needing to certify or re-certify for industry electrical codes for new construction, existing construction upgrades and maintenance, and post-lightning strike evaluation
  • Displays 0.1Ω to 1Ω resolution results on an easy to read LCD display for higher accuracy and readability than needle-driven analog instruments
  • Meeting structural electrical code standards greatly reduces the risk of personnel injury, power surges, and fire, increasing the overall safety of all occupants and equipment
