The Cryopak CTL is a contactless temperature data logger that works in conjunction with a mobile app. With a line-of-sight of approximately 30.5 meters, this compact device can record temperatures within a shipment as low as -40°C up to as high as 85°C.

The CTL has two logging modes, a 16KB memory, and comes with either an internal or external sensor. Five LEDs indicate the available temperature thresholds (High-High, High, OK, Low, and Low-Low), with additional LEDs for Status and RF Module. A plastic sealing keeps moisture out. Data reports can be downloaded in PDF, Excel, Text or Raw Data files.

Mobile app is available for Android OS 4.0 or higher and can be downloaded via Google Play.
