Product Features & Applications

Product Features:

  • The safety design complies with the IEC 61010-1 CAT.II 600V standard.It features multiple warning protections to prevent personal injury and equipment damage.
  • The measurement functions are diverse,capable of measuring grounding resistances ranging from 0 to 1999 Ω and grounding voltages ranging from 0 to 199.9 V,meeting the needs of various scenarios.
  • Equipped with LCD backlight display,low battery indication and LED warning light,the reading is clear and the status is intuitive.
  • By using a small test current (up to 3mA),the RCD will not be triggered,ensuring a safe and stable measurement process.
  • Supports 3-line precise measurement and 2-line simple measurement,adaptable to different grounding environments,with flexible measurement methods.
  • It has good adaptability to the environment,a wide range of working temperature and humidity,a small size and light weight,and is convenient to carry and use.

Product Applications:

  • Suitable for scenarios where the grounding resistance needs to be measured,such as the inspection of grounding systems for power equipment;
  • It can be used for measuring the grounding voltage,which helps in determining whether there is any abnormal voltage in the grounding system.
  • Supports precise measurement and is suitable for engineering acceptance checks where high accuracy of grounding resistance is required.
  • Simple measurement is applicable to places with low grounding resistance electrodes,such as the detection of grounding for metal water pipes.
  • Can be used in various environments,including different geological conditions such as wet or dry soil;
  • It can be used to check whether the grounding system complies with safety standards and ensure the safe operation of electrical equipment.
