Terra Extrem sensors are manufactured from special polymer resins. They are inspected before, during and after production (raw materials, manufacturing parameters, in-house laboratory tests and tests by independent bodies). As a result, you can be sure of the flawless reliability of the collection system, designed to last 100 years.
