Alatuji, Data Logger, Kelembaban Tanah, Suhu dan kelembaban tanah, data logger suhu tanah, alat uji suhu tanah, alat untuk mengukur kelembaban tanah

HOBO MX Soil Moisture Data Logger adalah satu-satunya logger kelembaban tanah yang terintegrasi penuh dengan biaya rendah di industri dengan pembongkaran data nirkabel Bluetooth. Tersedia dalam dua model – model yang mengukur kelembaban tanah (HOBO MX2306). Logger ini ideal untuk peneliti dan petani yang mencari data akurat yang mereka butuhkan untuk menghemat air, meningkatkan hasil panen , mengurangi limpasan berbahaya, dan melindungi ekosistem.

Hanya dengan ponsel, tablet, atau laptop Windows yang menjalankan aplikasi HOBOconnect gratis dari Onset, pengguna mendapatkan pengaturan nirkabel yang nyaman dan pengunduhan data melalui Bluetooth saat berada dalam jarak 100 kaki dari logger – memudahkan untuk mengambil data dari lokasi lapangan yang sulit diakses. Dan untuk area dalam ruangan, seperti rumah kaca, pengguna dapat menambahkan MX Gateway untuk akses jarak jauh ke data di perangkat lunak HOBOlink berbasis cloud Onset.
