T-Tissue: Tissue temperature (e.g., buds, cambium, wood) T-Surface: Surface temperature (e.g., bark) T-Soil: soil temperature or underwater temperature

The T-series sensors are used for direct, continuous and high-precision temperature measurements. The various T-series models are designed specifically to record internal temperatures (T-Tissue), outer/surface temperatures (T-surface) on plants and other measurement objects, or for soil/water temperature (T-soil). These devices are suitable for long-term application in outdoor conditions. Due to their extremely low power consumption, Ecomatik T-sensors are ideal for battery-powered solutions, e.g. in IoT applications.

    Like so many things, everything started with an idea ...

    In the case of the plant scientist and founder of ECOMATIK, Dr. Liu, it was the idea that modern measurement technology should enable crucial plant physiological parameters to be measured directly, precisely and with high temporal resolution on the plant itself. It was obvious to him that there is an information potential of immense value in the detailed understanding of immediate reactions of plants to their environment...
