I. GE Ultrasonic Scanner


1. About GE


While they’ve become one of the most respected brands in the digital non-destructive testing (NDT) space, GE has had to evolve from a general inspection arm of the Baker Hughes company to a specialized NDT arm of the business. After several decades and multiple business acquisitions, its portfolio of services has grown to include some of the most popular products today. With over 120 years of combined corporate experience, GE finds applications in several industries, including aerospace, automotive, oil and gas, electronics, and additive industrial manufacturing. Still, they’ve successfully incorporated advanced digital solutions into their inspections and NDT systems. Though headquartered in the US, it has regional representation in Europe, South America, and Asia.

III. GE vs. Olympus: Which is the Best for you?


The most important set of criteria that ensures the most benefits is often used to ascertain the best of the two brands highlighted above. This set of criteria is given below. 

  • Application – The range of applications is often essential as it helps reduce the need for a specialized scanner every time there is an inspection of a different material. While GE scanners have a decent range of applications, Olympus scanners have more range of applications making them more versatile. 
  • Accuracy – This is another essential criterion to consider since a lacking scanner accuracy will defeat the purpose of the quality inspection. The accuracy of both brands is pretty high, and periodic calibration can ensure high precision inspection.  
  • Reliability – The ability to deliver the required inspection activities to specification shows the scanner’s reliability. Both brands have a high level of reliability, but Olympus, with its range of highly durable models, seems better.
  • Cost – This criterion is often the most important for most individuals and companies. An uncompetitive price can discourage a customer from purchasing. Olympus prices seem to be more competitive for some models, especially those with manual operation. However, GE’s automated models also have more competitive prices than that Olympus’ models. 
  • Delivery Date – The turnaround time for delivery is critical as a delay in delivery can hinder the inspection objective of the customers. Olympus has a shorter delivery time than GE making them preferable in this category.
