Pencatat data suhu air yang tahan lama dengan resolusi 12-bit. Dilengkapi dengan sensor presisi untuk akurasi ±0,2°C, pencatat ini mengukur suhu antara -40°C dan 70°C (-40°F hingga 158°F) di udara dan hingga 50°C (122°F) di air. Casing tahan air dan ramping memungkinkan penggunaan yang lebih lama di air tawar atau air asin. Dan antarmuka USB optik memungkinkan Anda untuk mengunduh data bahkan saat pencatat basah atau di bawah air. Pelindung radiasi matahari diperlukan untuk mendapatkan pengukuran suhu udara yang akurat di bawah sinar matahari (baik Pelindung Radiasi Matahari RS1 yang perlu dirakit atau Pelindung Radiasi Matahari M-RSA yang sudah dirakit).
