The HI98319 is a compact, waterproof, pocket-sized marine Salinity tester designed for the measurement of salinity in salt water aquariums, aquaculture, brackish water, or other salt-water bodies.
HI98319 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.).
- Waterproof
- Automatic temperature compensation (ATC)
- Dual pin graphite EC probe
