1. Chart Recording Versus Data Logging
Real-time temperature monitoring requires constant feedback on the prevailing temperatures in the refrigerators. The chart recording setup includes a temperature measurement device attached to a recording chart.
Any temperature variation will cause the recording arm to deviate with a corresponding distance. The deviation reflects on the chart as either a rise or a fall. While chart recorders are easy to install and configure, they need chart replacements. Additionally, the user must physically go to the chart to check the readings and is consequently subject to human error.
Data loggers provide better performance for pharmaceutical quality control. They work by recording temperatures in the refrigerator and storing the data in a local storage device. The user can access the data logs by connecting the device to a computer and downloading the details.
Although data acquisition is continuous in this case, data access is not real-time. ELPRO provides advanced data loggers with connectivity features to overcome the real-time data access limitation.
Depending on the application, wireless IoT devices may be the best choice. These devices connect to the internet in case of multi-location facilities or the local area network in a single location facility. Additionally, they offer user-friendly and effective pharmaceutical quality control because they can connect to cloud storage.
