Ryan Systems' Smartphone-connected wireless temperature recorder

Ryan Systems Inc.’s new Emerald wireless temperature tracker connects to a smartphone via Bluetooth. Slightly larger than a wristwatch, the system monitors temperature-sensitive goods during transit and in storage. The temperature recorder stores up to 4,000 temperature readings and does not require any dedicated computer equipment or complex installations. The EmeraldView application for a smartphone connects wirelessly via Bluetooth to program Emerald devices, view data and optionally upload the information.
