I'm a technology guy. And, for anyone who hasn't taken the plunge or who has and have had disappointing results over the past few years with their Temperature monitoring system, you should really take a look at the SensoScientific Brand. www.Sensoscientific.com They have 2 system options: 900Mhz and a New WIFI introduction. Really cool advantages to this technology is that: You Don't have do deal with using, buying, providing, or maintaining a Server or Software! You will not have ugly wires and probe cables hanging off of your nice refrigerators because their entire wireless Transmitter goes inside your Refrigerator without drilling holes, etc. Your Notifications, Alarms, and documentation can all be accessed from ANY web-enabled device (Iphone, Ipad, personal Laptop, etc.) No need for dedicated Control station equipment. 100% web-based access to your information using your own Hospital Network Intranet. Give them a glance. www.Sensoscientific.com
