CANNON | The Standards that Set the Standard.

Use of high quality standards and reference materials ensures test reliability and accuracy. This is why the National Institute of Standards and Technology (NIST) delegated responsibility to CANNON for U.S. national standards for certified liquid viscosity reference standards in 2003.

Since 1938, Cannon Instrument Company has been a leader in viscosity measurement. With a broad range of viscosity standards and flash point reference materials that are available, CANNON standards calibrate and verify the performance of glass capillary viscometers, automated kinematic viscometers, rotational viscometers, falling ball viscometers, cup viscometers, tapered bearing simulator viscometers, and flash point testers. 

All CANNON viscosity standards are traceable to a NIST calibration and prepared in our ISO 9001-registered, A2LA-accredited laboratory. Visit our Quality Certifications page to learn more.
