Huazheng Factory HZ-5200 Contact Resistance Meter 200A Loop Resistance Tester
I. Introduction
The HZ-5200 is widely used for testing the contact resistance of various switches and electrical appliances, as well as the contact resistance of power cables and welding seams.The measurement data is accurate and reliable, with high stability, meeting the requirements of power supply departments for on-site high-voltage switch repairs and high-voltage switch factory contact resistance testing. The output current and measured resistance are displayed simultaneously on the 7-inch high-brightness touchscreen color LCD. Measurement results can be stored on a USB drive, with power-off storage functionality to ensure data can be queried at any time.
II.Specification
Mobile Phone Control: The instrument can be fully controlled through a dedicated mobile phone app. Test data is stored in a fixed format on the phone, making it easy to query data at any time.
