Temperature monitoring systems from Rees Scientific can monitor the temperature of cold storage (refrigerators, freezers, and ultra-low freezers) from +1300°C to -196°C as well as parameters such as humidity, differential pressure, and more. Users may receive notification via interactive phone, text, and email. The system can be wired, Zigbee wireless, WiFi, or a hybrid. The system can be installed on the facility’s network or on the ReesCloud, and is easily expandable to fit the user’s needs, including considerations for regulatory requirements such as GxP, FDA, CDC, USP <797>, USP <800>, and others.
