Irrometer Soil Moisture Sensor

Measure Soil Temperature

The 200TS sensor is a precision thermistor encapsulated in epoxy designed for direct burial, making it ideal for this application.

If used for air temperature measurements, care should be taken to properly expose the sensor in a shaded housing, such as a solar radiation shield, to provide airflow around the sensor and minimize direct exposure to sunlight, rain, and snow, ensuring that the air temperature inside the shield is a good representation of the outside air. Additionally, the potting compound will have an insulating effect that delays the sensor's response to temperature changes, which are faster in air environments compared to when buried. Features High precision Fast thermal response Low cost Small size Epoxy encapsulated High stability Long lifespan Operating Principle: The 200TS temperature sensor is a resistive device that responds to temperature changes. As the temperature rises, the resistance decreases. Once planted in the soil, it will change its resistive value as the soil temperature changes. The protective encapsulating material tends to insulate and slow down the response time when used for environmental measurements. The ohms-to-temperature relationship is constant and integrated into the reading devices used to interrogate the sensor. The 200TS temperature sensor is a precision thermistor encapsulated in epoxy for direct burial applications. Specification Information: The soil temperature measurement device or sensor will represent the temperature in degrees, using either the Fahrenheit or Celsius scale, when read with a compatible reading device. Its construction should be durable, resistant to deterioration in a moist soil environment, with an epoxy potting exterior surface and a corrosion-resistant plastic casing.
