Veriteq Instruments introduces vLog 4.3, its latest temperature validation system. The vLog 4.3 software permits automated and user- positioned limit lines on graphs, allowing for quick review of data relative to actual and expected limits. For a group of sensors, the software dynamically displays graphical markers of actual high, low, and average values. The user also can manually insert high- and low-limit lines for temperature and relative humidity to quickly see whether the environment was within specifications. The audit trail logs all changes to each file, providing a secure record of temperature, humidity, or other variables within a controlled environment. With events traceable to each specific logger, users have a complete and secure record of any modifications. Files from Veriteq loggers are encrypted in electronic records that meet 21 CFR Part 11 requirements.
