Deskripsi
Overview
Pencatat data yang terjangkau dan akurat yang mengukur konsentrasi oksigen di danau, sungai, muara, dan perairan pantai. Direkomendasikan untuk proyek penelitian biologi akuatik dan hidrologi, alat pencatat yang mudah dirawat ini menggunakan teknologi sensor DO optik RDO® Basic (Rugged Dissolved Oxygen).
Pencatat Oksigen Terlarut HOBO U26 merupakan bagian dari evaluasi multi-tahun pencatat dan sensor DO oleh Alliance for Coastal Technologies (ACT), yang hasilnya dipublikasikan di sini. Laporan yang tidak bias ini menjelaskan bagaimana kinerja HOBO U26 dalam kondisi laboratorium dan lapangan. Perhatikan bahwa surat tanggapan kami, dengan rekomendasi tambahan, dilampirkan di akhir laporan (halaman 58-59).
Features
- Affordable, high performance dissolved oxygen (DO) monitoring with 0.2 mg/L accuracy
- Optical DO sensor technology for long-lasting calibration with less maintenance
- HOBOware Pro’s Dissolved Oxygen Assistant software corrects for measurement drift from fouling; provides salinity-adjusted DO concentrations and percent saturation
- Optical USB interface for high-speed, reliable data offload
- User-replaceable DO sensor cap eliminates need to send logger back to the factory to replace membrane
NOTE: For DO measurements in saltwater, an adjustment for salinity is required. For waters with small changes in salinity (<2 ppt), a salinity meter reading typically provides enough accuracy. For environments with greater salinity changes, we generally recommend the HOBO U24-002-C Conductivity logger. If you need DO in Percent Saturation, barometric pressure data is required, which can be logged with a HOBO U20-001-04 Water Level logger.
