Megger DET2/3 Professional Earth Ground Tester Kit - 165 Foot test leads
The Megger® DET2/3 automatic ground test instrument is robust, compact and designed to measure ground electrode resistance and soil resistivity. It provides a full range of test methods and excels at the four terminal method of measurement, which eliminates the resistance of the current circuit from the measurement.
- High resolution of 1 mΩ, ideal for large ground systems
- Versatile test modes
- High accuracy for ground electrode grid and soil resistivity tests
- Rechargeable battery power that can last all day with a fast re-charge (up to 10 hours)
- Robust instrument with IP65 protection
- Automatic test frequency selection, with filters and high current features
- Diagnostic trace display
- Data storage - 900,000 points
- Large color display that shows numeric and graphical results
High accuracy earth (ground) measurements - The DET2/3 provides accurate 1 mΩ resolution measurements of ground electrode resistance. With its microprocessor controlled system, it provides a flexible and ‘user-friendly’ approach to ground tests by the provision of excellent error detection capabilities and full test information shown on a large color display. Test frequency, test current and filtering can be quickly and easily adjusted so that adverse conditions, which can influence the test, can be overcome. A wide band of test current frequencies, with a resolution of 0.5 Hz, can be used to eliminate errors caused by noise in the ground. The DET2/3 also includes an automatic frequency selection feature that scans for frequencies with the lowest noise level and then runs a test at that frequency. The selected test current frequency, test current level and the increased filtering option are stored in memory for use in subsequent tests
Trace display and data storage - Utilizing the latest processors, the DET2/3 can provide a live trace of its measurements, which graphically shows the amount of noise from the system under test - a powerful diagnostic tool for anyone doing ground testing. Use of the latest processors and a large internal memory allows for immediate calculations of resistivity (Wenner or Schlumberger method) and the ability to save a complete day’s worth of test results. Test result data can be downloaded directly through a USB flash drive or straight to a Windows PC running PowerDB™ software.
Weatherproof and rugged - The DET2/3 is sealed to IP54 standard, which provides weatherproofing during operation (case lid open). When the case lid is closed, its protection standard is to IP65 (water and dust damage). The case is made of a tough and light copolymer polypropylene, which can withstand the rough and tumble of outdoor use.
Portable power - An internal Li-ion battery provides for a full day of tests. The Li-ion battery has a fast recharge facility that allows a dead battery to provide an afternoon of tests, if charged during a lunch break. The DET2/3 can also operate from a standard 12 V DC battery supply.
