The TEROS 12 provides accurate, repeatable measurements of soil moisture, temperature, and electrical conductivity in a single rugged sensor. Its 70 MHz technology reduces errors from salinity and soil texture, while stainless steel needles ensure strong contact and minimal disturbance during installation. Designed for long-term field use, it’s maintenance-free, direct-burial rated, and built to deliver dependable data season after season.
Typical Uses:
- Soil and substrate monitoring in agriculture and research Irrigation management and optimization
- Greenhouse and nursery applications
- Environmental and soil health studies
- Long-term field installations requiring minimal maintenance
Key Features & Benefits:
- Measures soil moisture, temperature, and electrical conductivity (EC) in one compact sensor
- 70 MHz frequency minimizes salinity and texture interference for accurate readings across soil types
- Stainless steel needles provide strong EC contact and reduce soil disturbance
- Rugged epoxy-sealed body for long-term, direct-burial use Maintenance-free design with excellent long-term stability
- Wide measurement range suitable for diverse field and lab environments
