A unique feature of the newly designed series of premium tensiometers Model LM … is the large volume, robust tube and the sturdy, cylindrical clay tip. In addition to mechanical stability, the series has the advantage of having a longer use time (less maintenance) due to its larger capacity. Premium Insertion Tensiometers are suitable, in combination with a manometer or electronic sensor, for soil measurement in all desired depths of more than ca. 15 cm insertion depth. Tensiometer tubes generally project above the ground 8-10 cm. It is advisable to plan the total length correspondingly in order to avoid any unnecessary temperature influences caused by overly long, projecting tubes. With its various connection possibilities, the Model LM is suitable for use with switching sensors for controlling watering, as well as for on-site control when combined with a digital manometer.
