Amperimetro de Tenaza y Medidor de Resistencia a Tierra Mastech MS2301S (Clamp Meter Ground Resistance Tester Resistance detector / Megger / Meg Ohm Meter)


Because modern industrial electrical equipment has been quite popular, a good ground has become an important anti-interference, effective anti-lightning protection system. Therefore, safe, fast grounding measurement has become an urgent need. Clamp Earth Resistance Tester is a major breakthrough in traditional grounding resistance measurement without the use of auxiliary ground rods measuring, and need not interrupt the grounding device under test, simply grounding wire or rod clamp to live, you can safely and quickly measure resistance to ground.
In addition, the product can also make current measurements, the sensitivity of the clamp can measure the leakage current to 1mA, while the neutral current up to 20A RMS. This function is to be measured in ground loops when containing a large affect power quality and harmonic noise, it is particularly important.
In addition to the products used in industrial electrical equipment, also in power distribution, telecommunications, system configuration, construction and other fields have a wide range of applications ground.


  • MS2301 Clamp Earth Resistance Tester is used to measure any loop system grounding resistance,
  • For example, the grounding resistance grounding resistance power transmission lines and communication lines, electricity can also be measured
  • Equipment and lightning protection grounding resistance of grounding network. When a current ground loop interference,
  • Resistance measurement accuracy will be affected, then the available instrument for measuring ground resistance interference currents
  • The amount.
