What Our Customers Say

Digi-Shock XT was a perfect solution for monitoring & recording any potential high impacts to our sensitive hardware. The Digi-Shock was easy to set-up and use plus the mission software provided an excellent detailed report in graph format.  Impactograph technical / sales support was extremely helpful in determining the correct product for our specific requirements in addition to a quick turnaround getting the product.

M. Richman, Engineer, Space Dynamic Labs

SmartShip Live, provides outstanding data accuracy and reliability, delivered to us in real-time, so that we always know where our shipment is located and if there were any incidents. The real-time alerts are fantastic and helped us identify where and when an incident occurred. Excellent customer and technical support. They worked with us and provided us the right solution.  They go above and beyond to satisfy their customers’ needs.

J. Morgan, Logistics Manager, ABB

Digi-Shock G has given us a method to monitor and record impacts to our heavy cable products that can get damaged in transit if mishandled. The Digi-Shock mission control software allows us to see when impacts exceed our threshold for damage. This has been a great product for us and has helped minimize shipping damage. The support team at Impactograph is always helpful and friendly.

K. Naughton, Operations, Graybar

The Impactograph Analog Recorder provides excellent data accuracy and reliability for our transformer manufacturer customers. The ease of being able to review the data immediately is extremely beneficial for our customers to determine if there has been impact damage so appropriate action can be taken if required. Impact-o-graph’s customer support is always responsive and satisfies our needs.
