Testing

Our hands on Engineering Research and Development team builds quality into our JENSEN Marine products from the beginning by expertly designing each product from the ground up and validating all designs through extensive testing that is primarily conducted in our own on-site test lab. Therefore, JENSEN Marine Audio & Video products offer MORE durability and performance than you would expect from standard electronics.

Temperature/Vibration Chamber

Long duration product exposure to constant random frequency operational vibration and non-operational vibration to simulate rugged road conditions.  Simultaneous temperature cycle and vibration exposure are also conducted for additional data that is relevant to detecting potential material/component weaknesses and calculating product life expectancy.

 

 

 

 

 

High/Low Operating Temperature

Long-Duration product exposure to operational temperature extremes and rapid temperature cycles that are experienced in outdoor mobile applications. In addition, we test for High humidity introduced at high-temp to test the effectiveness of circuit corrosion protection (conformal coating).

 

High/Low Storage Temperature

Ensures our products will perform even after prolonged periods of storage with no power in extreme hot or cold temperatures.

 

Temperature Cycle

Used to ensure powered components withstand temperature fluctuations.
