Abstract A temperature and humidity measurement system at the KEK injector linac consists of 26 data loggers connected to around 700 temperature and humidity sensors, one EPICS IOC, and CSS archiver. CSS archiver engine retrieves the temperature and humidity data measured by the data loggers via Ethernet. These data are finally stored into the PostgreSQL based database. A new server computer has been recently utilized for the archiver of CSS version 4 instead of version 3. It can drastically improve the speed performance for retrieving the archived data. The long-term beam stability of linac is getting a quite important figure of merit since the simultaneous top up injection is required for the independent four storage rings toward the SuperKEKB Phase II operation. For this reason, we developed a new archiver data management application with a good operability. Since it can bring the operators a quick detection of anomalous behavior of temperature and humidity data resulting in the deterioration of beam quality, the improved temperature and humidity measurement system can be much effective. We will report the detailed system description and practical application to the daily beam operation.
