Roctest is a world leader manufacturer of high precision measuring and monitoring instrumentation for the civil engineering market and applications in the energy, healthcare and process control industries. Our products are sold in more than 75 countries by direct sales and through an international distributor network.
We have been in business since 1967 and are a publicly-traded company on the Toronto Stock Exchange where our shares trade under the symbol RTT.
Roctest’s products are used in civil engineering projects such as dams, tunnels and other large infrastructures, including tall buildings and mines. Our instruments measure pressure, bearing capacity, permeability, displacement, deformation and inclination. All products may be customized to fit our customers’ particular requirements.
In 1991, Telemac, a pioneer in vibrating wire technology and field instrumentation since its foundation in Paris in 1947, joined forces with Roctest. Recognized as a world leader, Telemac completes the Roctest product range with its line of measuring and monitoring equipment and inductive sensors.
In 1994, we acquired FISO Technologies, a manufacturer of fiber optic sensors and signal conditioners which measure strain, temperature, pressure, refractive index, displacement and force & load.
In 2006, Roctest acquired Smartec SA, a privately held Swiss company specializing in the development, production and distribution of measurement and structural health monitoring systems based on fiber optics. By acquiring Smartec, Roctest has become the only manufacturer of measuring instruments for the geotechnical and civil engineering markets to offer a complete set of technologies and solutions to meet the requirements of many challenging and demanding environments.
Our products are based on the vibrating wire technology, well-known and proven, and the state-of-the-art, fiber optic technology. Roctest offers an unparalleled range of products in multiple applications, for small and major projects and for every type of budget.
We have manufacturing facilities in: Quebec City (FISO Technologies), St-Lambert (Roctest Ltd), and Gretz-Armainvilliers near Paris, France (Telemac), and in Manno, Switzerland (Smartec).
Roctest designs, manufactures and markets sensors and high-precision measuring instruments for the civil engineering market and applications in the energy, healthcare and process control industries. We are recognized for our leading-edge technology, the quality of our technical expertise and our product development capabilities for challenging and demanding environments. 
Roctest and its subsidiaries, FISO Technologies, Telemac, and Smartec offer an unparalleled range of customized solutions combining both traditional vibrating wire technology and state-of-the-art fiber optics.
For just a fraction of the total investment cost in new or ageing infrastructure, whether a bridge, tunnel, dam, waterway, high-rise building, an industrial transformer, pipeline or even an oil tanker, our sensors and measuring instruments reduce the risk of damage to infrastructure and the environment, excessive wear and tear in machinery, and even loss of life.
Our leadership position in the research and development of cutting-edge ultra-miniature pressure sensors for applications in scientific research and healthcare reduces intrusive surgery, improves patient care and ultimately saves lives.
With offices in North America and Europe and a well-established distribution network in more than 75 countries, Roctest’s products are at work today in more than 100 countries around the world.
Roctest’s shares are listed on the Toronto Stock Exchange under the symbol RTT.
