Deskripsi
HOBO U23 Pro v2 External Temperature/Relative Humidity Data Logger U23-002A merupakan data logger weatherproof untuk memantau suhu dan kelembapan relatif. Sensor eksternal menggunakan kabel PVC sepanjang 184 cm. Desain sensor berdiameter kecil membantu pengguna mengukur pada ruang terbatas. Perangkat mendukung pengukuran suhu, kelembapan relatif, dan titik embun. Sensor kelembapan relatif yang dapat pengguna ganti memberikan respons cepat.
Sensor suhu bekerja pada rentang -40 hingga 70°C. Akurasi suhu mencapai ±0,25°C dari -40 hingga 0°C dan ±0,2°C dari 0 hingga 70°C. Resolusi suhu mencapai 0,04°C. Sensor eksternal mencapai waktu respons 3 menit 45 detik pada udara bergerak 1 m/detik. Sensor kelembapan relatif bekerja pada 0 hingga 100% RH dengan akurasi ±2,5% pada 10 hingga 90% RH. Resolusi kelembapan mencapai 0,05%, dengan waktu respons 15 detik pada udara bergerak 1 m/detik.
Logger bekerja pada -40 hingga 70°C dan menggunakan baterai lithium 3,6 V tipe 1/2 AA. Baterai memberikan masa pakai sekitar tiga tahun pada interval pencatatan minimal satu menit. Memori non-volatil berkapasitas 64K byte untuk sekitar 21.000 pengukuran suhu dan kelembapan. Pengguna dapat mengatur interval pencatatan dari satu detik hingga 18 jam. Antarmuka Optic USB membantu pengguna mengunduh data langsung dengan cepat. Pengguna dapat mengelola logger melalui perangkat lunak HOBOware dan HOBOware Pro.
