Data logger tahan cuaca yang dilengkapi sensor suhu dan kelembapan relatif bawaan. Sensor kelembapan relatifnya dirancang dengan daya tahan tinggi, sehingga sangat andal digunakan di lingkungan dengan tingkat kelembapan tinggi.
Informasi Penting:
Memerlukan software HOBOware serta Optic USB Base Station atau HOBO Waterproof Shuttle (U-DTW-1) untuk pengambilan data. Penggunaan HOBOware Pro diperlukan jika menggunakan HOBO Waterproof Shuttle.
