Fitur Teknik
- Persentase saturasi atau pengukuran konsentrasi (mg/L)
- Kompensasi suhu otomatis dengan kalibrasi suhu satu titik
- Kompensasi salinitas
- Memungkinkan penentuan langsung oksigen terlarut dalam air asin.
- Pengguna dapat mengatur nilai salinitas
- Batas waktu kalibrasi
- Tandai saat kalibrasi jatuh tempo pada interval yang ditentukan
- Perhitungan bawaan
- Mode Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR) dan Specific Oxygen Uptake Rate (SOUR)
- Barometer bawaan
- Kompensasi tekanan barometrik otomatis dengan kalibrasi 1 titik
- Menampilkan tekanan dalam unit yang dapat dipilih pengguna (mmHg, inHg, atm, psi, kPa, mbar)
- Kemampuan pencatatan data berkelanjutan (dengan interval yang dapat dipilih), log on demand, atau stabilitas
- Data GLP menyediakan data kalibrasi termasuk tanggal, waktu, tekanan, nilai kalibrasi, suhu dan nilai salinitas dari lima kalibrasi terakhir
- Konektivitas PC melalui USB Type-C yang diisolasi secara opto
- Menampilkan suhu dalam °C atau °F
- Sekitar 200 jam penggunaan terus menerus menggunakan 4 baterai AA
