This unit has all the same functions as the Tetis (S) Standard but has the additional ability to monitor humidity and reports on both dry and refrigerated land and sea containers. Especially beneficial for refrigerated containers (Reefers), carrying frozen or chilled cargo, Tetis R integrates a highly sensitive temperature sensor for monitoring the environmental temperature conditions with an accuracy up to ±0.2°C. For special handling cargo, such as medical syringes or hazardous substances the built-in accelerometer keeps you informed about changes in movement or events of impact, ensuring safe delivery of your cargo.
