TEMPERATURE & RH MAPPING

ISO 14644 is a standard that specifies the requirements for cleanrooms and controlled environments. It provides guidelines for air cleanliness, particle concentration limits, and other parameters to maintain a controlled environment.
To map temperature and relative humidity (RH) in various areas according to ISO 14644 using a Testo data logger, you would typically follow these steps:

1. Identify the areas: Determine the different zones or areas within your cleanroom or controlled environment that need temperature and RH mapping. These areas could include cleanrooms, storage rooms, manufacturing areas, or any other critical locations.
2. Determine the number of data loggers: Based on the size and complexity of the areas, decide how many Testo data loggers you will need to cover the required locations adequately. The number of data loggers will depend on the area’s size, the number of sampling points desired, and the level of detail you want to capture.
3. Position the data loggers: Place the Testo data loggers at predetermined locations within each area. Ensure they are positioned to measure temperature and RH accurately and representatively. Follow the ISO 14644 guidelines regarding the positioning of monitoring devices for your specific application.
4. Configure the data loggers: Set up the Testo data loggers according to the manufacturer’s instructions. Configure the loggers to measure temperature and RH at appropriate intervals. You may need to set the sampling frequency, logging duration, and other parameters based on your specific requirements.
5. Start the data loggers: Activate the Testo data loggers to begin recording temperature and RH data in the respective areas. Make sure the loggers are properly calibrated and functioning correctly.
6. Data collection: Allow the data loggers to collect data for the desired monitoring period. This period may vary depending on the ISO 14644 requirements or your specific needs. Ensure that the loggers are not disturbed or manipulated during this data collection period.
7. Retrieve and analyze data: Once the monitoring period is complete, retrieve the data from the Testo data loggers. Connect the loggers to a computer or use the designated software provided by Testo to extract the recorded temperature and RH data.
8. Analyze the data: Use appropriate software or tools to analyze the collected data. Check if the temperature and RH values meet the ISO 14644 requirements for the respective areas. Look for any deviations or anomalies that may require corrective actions or adjustments to the controlled environment.
9. Generate reports: Based on the data analysis, create detailed reports documenting the temperature and RH mapping results for each area. Include any observations, non-compliance issues, or recommendations for improvements.
10. Ongoing monitoring: Regularly repeat the temperature and RH mapping process to ensure ongoing compliance with ISO 14644 standards. Maintain a schedule for periodic monitoring and document the results for future reference.

Remember to refer to the ISO 14644 standard and the instructions provided by Testo for specific guidelines and best practices regarding temperature and RH mapping in controlled environments using their data loggers.
