Sensaphone introduces the Web600, a remote Web-based temperature monitoring system that provides continuous monitoring and reporting of critical temperatures for up to six temperature sensors. Completely stand-alone, its extended monitoring range allows it to be used for refrigerators, freezers, and ultra-low freezers with temperatures down to –80°C. Immediate alarm notification is provided via email and text message, and all status and programming is done through a convenient built-in Web page. With optional battery backup, the Web600 can operate for up to three hours during a power outage.
