HI98325 Low and High Range Salinity Tester • Waterproof • Automatic temperature compensation (ATC) • Dual pin graphite EC probe 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. HI98325 features amperometric graphite electrodes that provide improved repeatability in measurements as the pins do not oxidize. Additionally, this tester offers an exposed temperature sensor for faster response times and automatic single-point calibration. Salinity results are displayed in either parts per (g/L), Practical Salinity Units (PSU), or Specific Gravity (S.G.). Water salinity classes based on salinity levels Non-saline < 0.75 mg/L Moderately saline 0.75 to 1.5 mg/L affects crop productivity of salt-sensitive trees Highly saline 1.5 to 3.5 mg/L affects most trees Severely saline 3.5 to 6.5 mg/L affects salttolerant trees Exposed temperature sensor for faster response times Watertight seal An easily removable cover provides access to the battery compartment.
