Sterilization System Monitors Temps & Humidity

Automated Monitoring and Alarming Solution from dataTaker


CHESTERLAND OH, USA — CAS DataLoggers recently provided the temperature and humidity datalogging solution for a decontamination and sterilization facility using Ethylene Oxide (EtO) preconditioning rooms as part of its painstaking safety process.

The environment within these rooms needed to be continually monitored for both safety and quality assurance purposes, and the huge range of products sterilized required a minimum temperature of 22 ??C and a 40% relative humidity level. This 2-stage preconditioning process took approximately 12 hours.

The facility was looking for a monitoring solution which was easy to use, provided configurable alarms whenever conditions suddenly became unsafe, and which supported simplified data retrieval.

CAS DataLoggers supplied the facility with a unique system comprised of a dataTaker DT80 Intelligent Universal Data Logger and a workstation running a web browser. The data logger was then connected to temperature and humidity sensors to continually monitor the entire sterilization process.

In case the application ever needed to monitor additional rooms, the dataTaker data logger was expandable to 100 channels, 200 isolated or 300 single-ended analog inputs.

Users then configured multiple alarms within the datalogger to automatically alert staff whenever the preconditioning environmental conditions suddenly went outside acceptable levels.

Users could access the dataTaker web interface (dEX) directly through the web browser. The DT80???s dEX interface allowed users to configure the data logger, monitor the connected sensors, collect data, and remotely check the logged data and memory status–all from within a web browser.

Users scheduled the data logger to sample and record the temperature and relative humidity at five-minute intervals, using 15 single-ended sensors placed in the EtO preconditioning rooms.

The DT80???s built-in web server also allowed for remote access to logged data, configuration and diagnostics.
Users also made extensive use of mimics in dEX to visually monitor the progress of tests and to clearly identify to the facility staff when a test was currently in progress for a specific chamber.

The data was later downloaded from the datalogger and saved for quality assurance purposes in either CSV or DBD formats via dEX or a USB flash drive for easy data and program transfer.

The sterilization facility???s monitoring and alarming needs were all met using its intelligent dataTaker data logger.

The single DT80 was able to connect to both temperature and humidity sensors while being easy to use and to configure using its intuitive dEX interface.

The alarming capabilities helped to ensure a safe environment through quicker response times, and it was easy to retrieve all the data through the dataTaker???s remote monitoring and USB capabilities.

  1. No, we do not directly sell any products. Perhaps one of the many temperature & moisture sensor company vendors who regularly view our content do and will respond.

    We have made it a policy to add all appropriate requests for bid or product information entered as comment on this site to our comment list to help users find a suitable supplier and vice versa.

  2. We are looking for a humidity/temperature sensor which can be used in EtO gas filled chambers. Do you have this kind of sensor?
