For more than 5 decades Quartzlock have been specialising in measurement science, and building off-air (LF and GPS) and atomic (rubidium and hydrogen) frequency referencing standards and calibration equipment. Our products are used worldwide for referencing and calibration at the highest level in research and development, production testing, frequency referencing and time & frequency metrology. How have we achieved this position? We are an engineering-centric business – engineers run Quartzlock. It starts with design. Our research and development team constantly strive for the defining engineering solution to time and frequency challenges using analysis and modelling, circuit simulation and innovative design for product realisation. We then engineer a solution using state of the art materials combined with appropriate ergonomic and industrial design to create our own special blend of industry standard products and bespoke solutions. Our more parametric and accurate specifications, and lower limits of uncertainty save our customers time and money.
