Data Logger de Condutividade/Salinidade de água salgada (100 a 55.000 uS/cm)

Recursos destacados

• O sensor sem contato fornece longa vida útil
• Fornece acesso fácil ao sensor para limpeza e eliminação de bolhas de ar
• Duas faixas selecionáveis pelo usuário fornecem medições de 100 a 55.000 uS/cm.
• O compartimento Delrin evita corrosão em água salgada
• O software HOBOware Pro permite a calibração de ponto inicial/final para compensar qualquer incrustação e fornece conversão fácil para condutância e salinidade específicas usando a Escala de Salinidade Prática de 1978 (PSS-78)
• Interface ótica USB fornece descarga de dados de salinidade confiável e de alta velocidade em ambientes úmidos
• Compatível com o Shuttle Impermeável HOBO para recuperação e transporte de dados fácil e confiável

**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: 2 uS/cm
Temperature: 0.01°C (typical 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).
