WIKA IIoT Solutions, a WIKA partner, offers wireless temperature monitoring systems that easily attach to a facility\u2019s existing refrigerators, freezers, or ultra-low freezers. <\/strong><\/p>\n<p>Anyone who has kept up with the news knows that certain COVID-19 vaccines are extremely temperature-sensitive. If vials are left out too long at room temperature or even above 5\u00b0F\/\u221215\u00b0C (for Pfizer-BioNTech), the vaccine degrades and must be discarded.<\/p>\n<p>In fact, all vaccines require cold storage. Some must be kept in regular or ultra-low freezers, while others are compromised if the temperature drops below freezing. And of course, vaccines should not thaw and then refreeze.<\/p>\n<h2>Temperature Monitoring for Vaccines and Other Sensitive Products<\/h2>\n<p><span>According to the CDC\u2019s latest <\/span><a href=\"https:\/\/www.cdc.gov\/vaccines\/hcp\/admin\/storage\/toolkit\/storage-handling-toolkit.pdf\" rel=\"external\" target=\"_blank\"><span>Vaccine Storage and Handling Toolkit<\/span><\/a><span>, an effective cold chain has three components: well-trained staff, reliable storage and temperature monitoring equipment, and accurate inventory management. Guidelines for cold storage monitoring include:<\/span><\/p>\n<ul>\n<li><span> <strong>A temperature monitoring device (TMD)<\/strong><\/span><span> that records all temperatures at preset intervals, not just the daily max and min, and to keep the data for at least three years. This TMD must be highly accurate. The CDC recommends a digital data logger.<\/span><\/li>\n<li><span> <strong>Protect the cold storage unit\u2019s power supply.<\/strong><\/span><span> This means making sure the unit is not accidentally unplugged or has its fuse tripped.<\/span><\/li>\n<li><span> <strong>Safeguard the door.<\/strong><\/span><span> An open door not only raises the refrigerator or freezer\u2019s internal temperature, but it also allows light to enter, which could lead some vaccines to degrade.<\/span><\/li>\n<\/ul>\n<p><span>Other sensitive items also require accurate temperature monitoring. Many biological products \u2013 reagents, lab samples, insulin, tissue samples, etc. \u2013 are stored at cold and ultra-cold temperatures. And to a lesser degree, but no less critical, frozen and refrigerated food stock need to be monitored almost as carefully. A door left open or a power outage is not only a health hazard but can also be costly, so accurate tracking and monitoring is crucial. To ensure product effectiveness and safety from manufacturing plants to the end user, storage units must be able to maintain a steady temperature.<\/span><\/p>\n<p><span>Some pharmaceutical-grade units are equipped with continuous monitoring systems that meet CDC guidelines and industry best practices, but what do you do if your cold storage unit doesn\u2019t have these features built in? You need a simple yet sophisticated temperature monitoring system.<\/span><\/p>\n<h2>Breakthrough Ease and Reliability in Cold Storage Monitoring<\/h2>\n<p>WIKA has a <a href=\"https:\/\/blog.wika.com\/us\/\/applications\/wika-partners-with-phase-iv-engineering-to-offer-innovative-iiot-solutions\/\">majority investment in WIKA IIoT Solutions<\/a>, a company that offers remote sensing and IIoT (Industrial Internet of Things) solutions.
