Operate confidently in cold environments, even as low as -29°C. The ruggedly designed Model 786 takes laboratory level performance into the harshest of environments.

Unlike other calibrators that cannot be used in the extreme cold, the 786 boasts an active internal environmental control system, specifically tailored for those calibrating in cold rooms and freezers. Initially crafted for the rigorous demands of the US Navy, it conforms to stringent military standards, undergoing bench, bounce, and altitude testing. Encased in a high-impact resistance shell, its removable lid conveniently houses all the essential accessories.

Beyond its robust design, Model 786 is unparalleled in protection and functionality, offering unique reference channel input options, datalogging, and other advanced features.
