Features & Benefits

Introducing the Model 6200A Cryogenic Current Comparator Bridge (CCC) from Measurements International (MI) – the ultimate solution for achieving the highest level of resistance calibration accuracy. With an uncertainty of less than 3 parts in 10-9, our CCC surpasses all other technology on the market.

Since 1987, MI has been a leader in providing the most accurate DCC room temperature resistance bridges, allowing customers to achieve unbeatable accuracy levels. However, with the introduction of the Model 6200A CCC, we are proud to take your resistance calibration capabilities to new heights.

The 6200A CCC utilizes leading edge technology to remove the need for a liquid helium supply to operate.  The re-condensing system operates off the initial supply of helium gas and runs continuous after that.

Designed by Dr. Carlos Sanchez, a renowned expert in precision electrical metrology with years of experience in CCC Bridges and Quantum Hall Resistance Standards (QHR), the Model 6200A is the ultimate choice for metrology laboratories. Don’t settle for anything less than the best – trust MI to deliver unmatched accuracy and precision. Upgrade to the Model 6200A today.
