The HI98325 is a compact, pocket-sized salinity tester designed to measure salinity levels in irrigation water.
The 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.
HI98325 features an exposed temperature sensor for faster response times and amperometric graphite electrodes for improved measurement repeatability (pins do not oxidize
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)
