Light, Pressure, Temperature data Logger

Overview of LoggLaw C7
LoggLaw C7 is a new data logger that collects and stores depth, temperature and  light data. LoggLaw C7 has a highly accurate clock (±95sec maximum per year with automatic temperature compensation) which realizes more precise geolocation. There are two temperature sensors inside the logger and outside the logger at the tip of the stalk. LoggLaw C7 is smaller and more power-efficient than the LoggLaw C6. LoggLaw C7 can be flexibly customized with the stalk length, presence / absence of stalk, temperature sensor position, battery size and logger size.
