Manufacturing
Gordon utilizes the latest technology available for pick and place manufacturing to ensure repeatability, accuracy, and scalability. Each individual component is x-rayed for quality assurance before being installed on the PCB. The automated modern manufacturing method eliminates 90% of possible human error and standardizes product expectations with repeatable precision.
Quality Assurance
Much more than a 10 pin break-out-box, the automated QA/QC inspection routine checks every single board connection and component lead for manufacturing defects. Historically, this in-circuit test was performed using a “bed of nails” test fixture, but as the mesmerizing video shows, we are redefining MWD QA/QC with world class robotics and standardizing product delivery.
Sensors
Traditional quartz-based accels are expensive, heavy, and prone to failure. MEMS devices are much smaller, 10x more robust, and a fraction of the cost. So why isn’t everyone using these? MEMS devices notoriously struggle with accuracy at temperature; however, after 4 years of R&D, our scientists had a technological breakthrough and our patented algorithms now allow you to get all the benefits of solid-state technology without sacrificing the accuracy at the temperature you demand. The GT-DM contains an array of rugged sensors that are fit for purpose. The right tool for the right job.

Repair And Maintenance
The GT-DM’s 2 PCB design allows us to bring a consumer electronics approach to MWD. Gone are the days of calling in a television repair technician to repair individual components on your electronic devices. When service is needed, we replace the entire tool, zeroing out all hours on every component.
