Deskripsi

Overview

Sensor nirkabel pemenang penghargaan yang bekerja dengan sistem HOBOnet untuk mengukur kelembapan tanah dan suhu tanah pada berbagai kedalaman dengan satu probe. Dengan pemasangan yang cepat dan mudah, sensor tahan lama dan probe 3 segmen ini mengukur hingga kedalaman 45 cm (18 inci).

Dilengkapi dengan teknologi TDT5 GroPoint dengan desain antena yang telah dipatenkan, sensor ini mengukur kelembapan tanah di sepanjang setiap segmen probe, sehingga menghasilkan volume pengaruh terbesar per bagian pengukuran. Frekuensi pulsa yang tinggi per pengukuran memberikan data kelembaban tanah yang tepat dan konsisten.
