Ecomatik - T-Series - Agriculture Monitoring - Temperature Sensors
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.
For size and other model characteristics, see specifications.
