Waterproof Salinity Tester Low and high range – HI98325

The HI98325 is a compact, pocket-sized, salinity tester designed to measure salinity levels in irrigation water.

 

This waterproof tester is the ideal tool in agricultural areas such as coffee farms, orange farms, watermelon farms, tea and rice farms where level salinity values are vital to crop management. Additionally, the HI98325 is useful in industries such as printing, textiles, food and beverage as well as research and environmental protection institutes where low level salinity values are needed.

 

To provide the best resolution and accuracy for each measured sample, the tester defaults to the Auto range mode where High or Low range is automatically selected. Additionally, users can opt to manually configure High or Low reading mode in Setup.

 

Results are displayed in parts per thousand (ppt), Practical Salinity Units(PSU), or Specific Gravity (S.G.).
