Deskripsi
Sensor nirkabel ini bekerja dengan sistem HOBOnet untuk mengukur kelembapan tanah (kadar air volumetrik), suhu tanah, dan konduktivitas listrik. Desainnya yang tahan lama memungkinkan sensor bertahan hingga 10 tahun di lapangan. Ujung probe baja tahan karat yang diasah memudahkan pemasangan, bahkan di tanah keras, dan volume pengaruh yang lebih besar meningkatkan akurasi. Teknologi kapasitansi 70MHz membantu meminimalkan efek salinitas dan tekstur tanah.
Sistem HOBOnet menyediakan jaringan sensor nirkabel yang hemat biaya dan dapat diskalakan untuk pemantauan kondisi lapangan melalui web. Anda dapat memantau beberapa titik dengan satu sistem, tanpa perlu kabel panjang yang bisa mengganggu atau menarik petir. Sensor ini mudah dihubungkan ke jaringan, dan pengguna dapat mengakses data melalui HOBOlink®, platform cloud dari Onset.
Kami menyarankan Anda memakai Klip Verifikasi untuk memeriksa pengoperasian dan akurasi sensor HOBOnet T11 dan T12. Memasang klip ke sensor akan menunjukkan tingkat kelembapan tanah yang diketahui. Anda tidak perlu menguji sensor langsung di tanah, sehingga bisa menghindari proses pengeringan sampel tanah di oven.
