A little History...

DJB Instruments UK Ltd has been manufacturing accelerometers, cables, instrumentation and accessories for over 40 years.  Originally established as DJ Birchall Ltd in 1974, it changed name in 2010 after the death of the company’s founder, Don Birchall.  After some major restructuring and re-investment, the company is now enjoying a period of expansion with truly global aspirations.

DJB is proud to uphold the traditions of quality British manufacturing that has been admired for so long around the world and also maintains the fundamental engineering innovation that Don Birchall was well renowned for. Still the only global accelerometer manufacturer using the Konic Shear™ design patented by Don and offering significant improvements in performance and cross axis reduction, it continues future innovation through joint academic research programs and internal material developments.
