About CANNON

Since its founding in 1938 by scientist, inventor and educator Dr. Michael R. Cannon, CANNON® Instrument Company has earned international acclaim for the quality of its viscosity-related products and services. The company's longstanding emphasis on production of premiere-quality test equipment has kept CANNON at the cutting edge of research and development for viscosity instrumentation serving a variety of industries.

We are proud of our unique alliance with NIST (National Institute of Standards and Technology). As a NIST delegate for provision of U.S. national measurement standards in the field of viscosity measurement, CANNON can offer our customers unique assurances of the quality of our products. We also provide testing and certification for customer samples, and we have the capability to produce custom blend viscosity/density standards to your specification.

The CANNON Difference

We've spent years pioneering viscosity measurement technologies and improving measurement precision.

In 1938 we introduced our first manual glass viscometer. Since then, we've helped generations of customers to achieve improved measurement accuracy and throughput in their laboratories… increasing their return on products with tighter measurement precisions and fast automation.

Our instruments are made to uphold the CANNON tradition of excellence—engineered to take on both the simplest and most challenging applications with equal ease. They're designed with features that make life in the laboratory simpler, safer, and faster. And they're built with components that work hard and last for years.

Every product that CANNON offers has been carefully crafted to meet or exceed specifications required by international standards organizations including ASTM, SAE, ISO, and AASHTO. Our major equipment items are CE Mark compliant. All CANNON Certified Viscosity Reference Standards are traceable to NIST.

Our staff maintains professional contact with industry experts in the fields of petroleum and petrochemicals, polymers, asphalt and paving, and many other areas. We also maintain a presence at national and international conferences and exhibitions serving our customers. Our quality processes and goals emphasize our ongoing commitment to customer satisfaction.
