Deskripsi
HOBO Water Temp Pro v2 dapat bertahan lama dengan resolusi 12-bit. Dilengkap dengan sensor presisi untuk akurasi ± 0,2 ° C, data logger ini mengukur suhu antara -40 ° C dan 70 ° C (-40 ° F hingga 158 ° F) di udara dan hingga 50 ° C (122 ° F) di dalam air. Casing kedap air dan ramping memungkinkan pemantauan yang lebih lama dalam air tawar atau air asin. Selain itu, antarmuka USB optik Water Temp Pro v2 memungkinkan untuk memuat data meskipun logger basah atau di bawah air. Pelindung radiasi matahari diperlukan untuk mendapatkan pengukuran suhu udara yang akurat di bawah sinar matahari (RS1 Solar Radiation Shield, diperlukan perakitan; atau M-RSA pra-rakitan Solar Radiation Shield).

IMPORTANT
-
The plastic case will become brittle at temperatures lower than -20°C. If the logger is deployed in a location where the temperature drops below -20°C, make sure the logger remains stationary and is not pulled on or struck. Return the logger to above -20°C before handling.
