HOBO U23 Pro v2 Temperature/Relative Humidity Data Logger

Overview

Discontinued 

Data logger tahan cuaca yang dilengkapi sensor suhu dan kelembaban relatif bawaan. Sensor kelembaban relatif dirancang lebih tahan lama dan andal saat digunakan di lingkungan dengan tingkat kelembaban tinggi.

Informasi Penting
Memerlukan software HOBOware serta salah satu perangkat berikut: Optic USB Base Station atau HOBO Waterproof Shuttle (U-DTW-1). Khusus penggunaan HOBO Waterproof Shuttle, diperlukan HOBOware Pro. Silakan lihat daftar perangkat yang kompatibel di bawah ini.

Data logger tahan cuaca yang dilengkapi sensor suhu dan kelembaban relatif bawaan. Sensor kelembaban relatif memiliki daya tahan yang sangat baik sehingga tetap andal digunakan pada lingkungan dengan tingkat kelembaban tinggi.
