Description

Overview
Pencatat data yang hemat biaya untuk mengukur salinitas, konduktivitas, dan suhu di lingkungan air asin dengan perubahan salinitas yang relatif kecil (±5.000 μS/cm) seperti teluk air asin, atau untuk mendeteksi peristiwa salinitas seperti upwelling, hujan badai, dan pelepasan air. Data dari pencatat ini dapat digunakan dengan data dari Pencatat Oksigen Terlarut HOBO U26 untuk memantau persen saturasi oksigen terlarut.

Catatan: Saat memantau salinitas di perairan dengan variasi lebih dari ±5.000 uS/cm, lihat keakuratan yang ditunjukkan pada Plot C dalam spesifikasi produk untuk menentukan apakah keakuratannya dapat diterima untuk kebutuhan Anda.

Features
​Non-contact sensor provides long life
Easy access to sensor for cleaning and shedding air bubbles
Two user-selectable ranges provide measurements from 100 to 55,000 uS/cm.
Delrin housing will not corrode in saltwater
HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity using the Practical Salinity Scale 1978 (PSS-78)
USB optical interface provides high-speed, reliable salinity data offload in wet environments
Compatible with the HOBO Waterproof Shuttle for easy and reliable data retrieval and transport
Non-contact sensor with titanium pentoxide coating keeps the sensor from coming in contact with the water, thereby preventing tarnishing or corrosion associated with traditional electrode sensors; sensor coating is inert, so fouling can be wiped off easily

Measurements: Actual Conductivity, Temperature, Specific Conductance at 25C (calculated), Salinity (calculated using PSS-78, the Practical Salinity Scale 1978)Conductivity Measurement Range (Calibrated Range) High range: 5000 to 55,000 uS/cm Low range: 100 to 10,000 uS/cm Over the range of 5 to 35C (41 to 95F)Temperature Measurement Range: 5 to 35C (41 to 95F)Specific Conductance Accuracy (in Calibrated Range using Conductivity Assistant and Calibration Measurements) Low range: 3% of reading or 50 µS/cm, whichever is greater High range: 5% of reading, in waters within a range of ±3,000 µS/cm; waters with greater variation can have substantially greater error (see Plot C) Conductivity Resolution: 2 uS/cm Temperature Accuracy: 0.1°C (0.2°F) at 25°C (77°F) Temperature Resolution: 0.01°C (0.02°F) Conductivity drift: Up to 12% sensor drift per month, exclusive of drift from fouling. Monthly start- and end-point calibration should be used with the HOBOware Conductivity Assistant to achieve the specified Specific Conductance accuracy. Response time: 1 second to 90% of change (in water) Operating range: -2 to 36C (28 to 97F) – non-freezing Memory: 18,500 temperature and conductivity measurements when using one conductivity range; 11,500 sets of measurements when using both conductivity ranges (64 KB total memory) Sample rate: 1 second to 18 hrs, fixed or multiple-rate sampling with up to 8 user-defined sampling intervals Clock accuracy: +/- 1 minute per month Battery life: 3 years (@ 1 min logging) Maximum depth: 70 m (225') Weight: 193 gm (6.82 ounces), buoyancy in freshwater: -59.8 gm (-2.11 ounces) Size: 3.18 cm diameter x 16.5 cm, with 6.3 mm mounting hole (1.25" diameter x 6.5", ¼" hole) Wetted housing materials: Delrin housing, epoxy, stainless steel retaining ring, polypropylene, Buna rubber O-ring, titanium pentoxide (inert coating over sensor) – all materials are suitable for long-term use in saltwater.CE compliance: The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).
