Ethylene Oxide Sterilization Temperature and Humidity Verification Instrument

        Ethylene oxide sterilization temperature and humidity verification instrument DT-220PRO has a unique dual-cavity design, safe and stable, with its own brick Lee, through the CE certification, measurement, reliable data, domestic recognition. The product is compact in size, the sensor probe is durable and corrosion-resistant. The product battery-powered, independent work, you can pre-set the start time, and then they are placed in different measurement positions, the collected temperature and humidity data with a time node, you can display the temperature and humidity change curve of each point under the same time coordinate, easy to analyze and compare the data, the DT-220PRO Ethylene Oxide Sterilization Temperature and Humidity Verification Instrument is widely used in the sterilization of Ethylene Oxide ET0 / EO sterilization Temperature and humidity verification, provide sterilization process complete temperature and humidity change curve and report, export PDF verification report, with tracking design, data can not be tampered with.

        Ethylene oxide is a broad-spectrum sterilizing agent, flammable and explosive, with strong penetrating ability, most of the items that should not be sterilized by general methods can be sterilized and disinfected with ethylene oxide, e.g.: electronic instruments, medical devices, books, etc. It is one of the main low-temperature sterilization methods at present*. The killing process of ethylene oxide is called "alkylation", which is irreversible to the role of molecules in the cell, making the molecules lose their role, the cell is no longer replicated, resulting in cell death to achieve the effect of sterilization. The main factors affecting ethylene oxide sterilization are ethylene oxide concentration, humidity, temperature and time.

        Ethylene oxide sterilization cabinets need to be verified periodically to check whether their performance meets the design requirements. When the appearance and performance of the sterilized items have changed significantly, it is also necessary to re-design the loading method and sterilization process, and the uniformity of the sterilization chamber temperature and the detection of humidification effect is an important part in the verification process.

        When the verification of ethylene oxide sterilization, you need to use more than one verifier placed in the sterilization chamber at the same time in different locations, the verification of special software can be convenient to pre-set these verifiers the same sampling rate and start time, so that the collected temperature and humidity data with a time stamp at each point has the same time coordinates, easy to compare and analyze, and each verifier will automatically generate the test point throughout the sterilization process temperature and humidity curve. Each validator will automatically generate the temperature and humidity curve of the test point throughout the sterilization process. Ethylene oxide sterilization cabinet needs to be verified periodically to check whether its performance meets the design requirements, when the appearance and performance of the sterilized items have significant changes, but also need to re-design the loading method and sterilization process, in the verification process of the sterilization room temperature uniformity and humidification effect of the test is an important part of the process.

        Since the sterilization data and records need to be kept for a long time, the chemical monitoring method and biological monitoring method can not well meet such requirements, which requires us to use an independent, wireless recording instrument to automatically record the temperature and humidity data of the whole sterilization process, which are time-stamped, and can be imported into the computer for statistical analysis and saved in the form of electronic documents.
