Salinity Chemical Test Kit - HI3835

The HI3835 is a chemical test kit that measures salinity by mercuric nitrate titration. The HI3835 is supplied complete with all of the reagents and equipment necessary to perform approximately 110 tests.

  • Pre-made reagents for ease of use
  • All reagents marked with expiration date and lot number for traceability
  • Manual titration performed with diphenylcarbazone indicator


The HI3835 is a titration-based chemical test kit that measures salinity within the 0.0 to 40.0 g/kg range. The HI3835 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 110 tests.

Features at-a-glance

  • Complete setup
    • All required materials are included with the test kit, such as the sample vial, indicator and reagent bottles, and calibrated syringe.
  • High resolution
    • Readings from 0 to 40 g/kg are determined to 4 g/kg resolution for each 0.1 ml of titrant added.
  • Replacement reagents available
    • There is no need to buy a new kit when reagents are exhausted. The HI3835-100 can be ordered to replace the reagents supplied with the kit.

Significance of Use

Salinity is defined as the total solids in water after all carbonates have been converted to oxides, all bromide and iodide have been replaced by chloride, and all organic matter has been oxidized. The salinity value is in g/kg or ppt (parts per thousand). The monitoring of salinity is essential for industrial waste and seawater, as different species of plants and animals thrive varying salinity levels.
