A soil moisture meter that can be used for a long time. Ideal for measuring moisture levels in plant cultivation and embankments.
HD-001 is a soil moisture meter using a measurement method called the tension meter method. A porous ceramic cup is buried in the soil, and when the surrounding soil dries out, water from inside the container is drawn out through the porous cup, creating negative pressure inside the container. This negative pressure (suction pressure) is used to determine the soil moisture content. - The sensor part is highly accurate and environmentally friendly. - Each component can be detached (air tank part, pressure sensor part, PC pipe part, porous cup part). - It can be observed for a long time without water replenishment. - Pipe length can be specified and extended.

basic information
?Features? The air tank allows for measurements to be taken for an extended period without the need for water replenishment. The negative pressure sensor is a high-precision semiconductor pressure sensor that offers excellent stability, consumes low current, and is ideal for battery operation. It consists of a tank section, a negative pressure sensor section, a pipe section, and a porous cup section, with each part being detachable, resulting in very good maintainability.
