LUL “Logger Ultra Léger” - Ultra Light Logger

The LUL is the tiniest bio-logger of the family. While measuring temperature, light and pressure every minute, it provides a 1.5 years life time for a total weight (including batteries and casing) of just 2.0 grams. Casing is customizable according to the intended use (biocompatible casing for implantation or pressure resistant for deep diving use) ; the size and nature of batteries can be adapted to the application and the temperature conditions.
