| Electric Tool Life Tester |
Electric Tool Life Tester loads various periodic signals, such as constant current, constant torque and revolving speed etc, to a single electric tool until it is completely ruined, comparing historical data for further causal analysis.
Accomadative to the charcteristics of the industry, Jumho Electric has a product especially designed to test the life of electric tools, using one host computer to control hundreds of life testers timely and automatically.This host computer can store real-time curve and invocate historical data of every tester and realize web publishing. |
Main System Framework |
Using CAN bus to connect and control Electric Tool Life Tester designed by Jumho Electric forms an enormous CN Control Network.
