VersaTrak offers patent-pending, auto-NIST calibration (ANC), which allows for prescheduled or on-demand automatic NIST calibration tests for any single or group of sensors at no additional cost. VersaTrak will automatically provide all the reports needed to prove the accuracy of the system to any regulator. All reports are archived and can be reviewed and printed at any time. Proving system accuracy is an important aspect and can be a large ongoing expense of a temperature monitoring system.
