Overview
HDC-20A40A/50A grounding down lead conductivity tester is widely used for measuring the
contact resistance of various switches and electrical appliances, as well as the contact
resistance of cables, wires, and welds, meeting the requirements of the power department for
contact resistance testing.
Advantage
♦ The instrument is controlled by high-speed microcontroller, with a high degree of automation and easy operation.
♦ The instrument adopts a new power supply technology, with multiple current ranges and a wide measurement range.
♦ Intelligent power management technology ensures that the instrument always operates at the minimum power state, effectively reducing internal heating and saving energy.
♦ Adopting a 7-inch high-definition touch screen, it can freely switch between Chinese and English.
♦ The instrument comes with a perpetual calendar clock and power down storage, which can store 1000 sets of test data and can be viewed at any time.
♦ The instrument is equipped with RS232 and USB interfaces, which can communicate with computers and store on a USB flash drive.
♦ Download a dedicated app for mobile phones, operate instruments through dedicated software, upload test data, and facilitate queries.
