DTH-121 seriesSoil temperature moisture conductivityThree-in-one transmitter
Directly and stably reflect the true moisture content of various soils
The DTH-121 series soil temperature, moisture, and conductivity three-in-one transmitter can directly and stably reflect the true moisture content of various soils by measuring the dielectric constant of the soil. It can measure the volume percentage of soil moisture and is a soil moisture measurement method that complies with current international standards.
■ It can be used to determine the conductivity of water and fertilizer integrated solutions, as well as other nutrient solutions and substrates.
■ The electrodes are made of specially treated alloy materials, which can withstand strong external impacts and are not easily damaged.
■ Completely sealed and resistant to acid and alkali corrosion, it can be buried in the soil or directly put into water for long-term dynamic testing.
■ High accuracy, fast response, good interchangeability, probe insertion design ensures accurate measurement and reliable performance.
Application fields
■ Smart agricultural greenhouse
■ Flower culture
■ Edible fungi cultivation
■ Breeding pen
■ Aquarium
■ Exhibition halls and museums
■ Conference center
■ Indoor stadium
