HOBO 盐水电导率/盐度数据记录仪

空白

测量值

Actual Conductivity, Temperature, Specific Conductance at 25C (calculated), Salinity (calculated using PSS-78, the Practical Salinity Scale 1978)

电导率测量范围

Low range: 100 to 10,000 uS/cm

High range: 5000 to 55,000 uS/cm

电导率校准范围 - 温度范围

5°C至35°C

41华氏度至95华氏度

电导率扩展范围

Low range: 100 to 10,000 uS/cm

High range: 5000 to 55,000 uS/cm

(readings below these ranges reported as 0)

温度测量范围

-2°C至36°C

28°至97华氏度

电导率准确度（在使用电导率助手和校准测量的校准范围内）

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

电导率分辨率

2 uS/cm (typical)

温度精度
