Veinasa-TWSD integrated temperature and humidity conductivity sensor has stable performance and high sensitivity. It is an important tool for observing and studying the occurrence, evolution, improvement and dynamics of saline soil. Soil temperature, soil moisture and soil conductivity can be measured simultaneously; by measuring the dielectric constant of the soil, the true moisture content of various soils can be directly and stably reflected. The soil moisture sensor measures the volume percentage of soil moisture and is a soil moisture measurement method that meets current international standards.

Veinasa-TWSD has the following characteristics:
(1) Three parameters of soil temperature, soil moisture and conductivity are combined.
(2) It can also be used for the integration of water and fertilizer solutions, as well as the conductivity of other nutrient solutions and substrates.
(3) The electrode adopts specially treated alloy material, which can withstand strong external impact and is not easy to damage.
(4) Completely sealed, resistant to acid and alkali corrosion, can be buried in the soil or directly into the water for long-term dynamic detection.
(5) High precision, fast response, good interchangeability, probe plug-in design to ensure accurate measurement and reliable performance.
(6) Perfect protection circuit.
(1) If the sensor is used with our data logger, it can be directly connected to the corresponding interface of our data logger.
(2) If buy separate transducer, the transducer supporting lines sequence respectively to:
| Line Color | Output signal |
