03 Mar 2025 Mandatory Update to LogTag Version 3
Update by March 28, 2025
Digital Data Loggers (DDLs) provided by the Philadelphia Department of Public Health (PDPH) use LogTag software to download temperature data.
LogTag version 2 is no longer supported and may cause data reporting errors. Therefore, all providers who use PDPH-provided DDLs must update their software to LogTag version 3 by March 28, 2025.
