Keyland Solar Testing Equipment for Solar Module Weld Crack Testing 

Keyland has researched and developped  "Electroluminescent" of solar photovoltaic module defect detection equipment, its highly sensitive infrared camera can detect defective solar module, which can help users know the solar module and panels from defects in material or workmanship defects.

The equipment can be applied before and after  lamination process  , Defect Detector  is an important and effective process monitoring and testing equipment.

It consists of a set of specialized optical imaging systems, and high-sensitivity camera module, which is available to users in the the preparation process, product quality testing.

Electric control part: The main control system of device is  relay ;Electronic control components including: relays, contactors, solenoid valves, lights, etc

Pneumatic part:cylinder 

Test Power:0~20A    0~100V
