TEC-100
The TEC-100 is a combined sensor for determining the soil temperature (°C) and the electrical conductivity (mS/cm) of the soil and is designed for connection to data loggers via cable. The data logger supplies the probe with power and stores the measured values. From the logger, the data is output via an interface cable to a laptop or via remote data transmission. This design is particularly suitable for measuring sites with several soil sensors (in connection with a data logger) and long-term measurements (e.g. measuring sites, lysimeters).
The TEC-100 consists of a waterproof cast plastic housing and can be completely buried for deep or horizontal installation. The measuring rods (antennas) are made of stainless steel. Data acquisition can be analog or digital (RS485).
