New type high current switch (certified by the third party) is adopted to save the bulky vacuum box, and high stability alloy is used as resistance material,

Temperature drift < 5% FS was achieved to ensure the credibility of the experiment.

The device has three relatively independent control modes: remote PC + touch screen + remote control. The current, voltage, temperature and other parameters can be displayed and recorded

There are total voltage, single voltage, temperature, data record and data curve;

Large current short circuit switch, low power, energy saving and environmental protection, with dual protection system, intelligent temperature protection, arc extinguishing and rust prevention

All control parameters setting, data acquisition and video recording of remote control and monitoring system can be operated by a computer more than 30m away from the equipment;

The equipment can be compatible with gb31241. GB / t31485, GB / t31467.3, iec62660-2018 and other domestic and foreign standards.
