Hanna Instruments HI-98319 Waterproof Salinity Tester
Hanna Instruments HI-98319 Waterproof Salinity Tester
Our new HI-98319 waterproof salinity and temperature tester is perfect for any saltwater aquarium. A more accurate alternative to refractometers, this tester uses conductivity to determine salinity levels of natural and artificial seawater. Ideal for testing salinity in salt water aquariums, it is quick and easy to use and provides digital readout of both salinity and temperature.
Salinity results are displayed in either parts per thousand (ppt), Practical Salinity Units (PSU), or Specific Gravity (SG). Our marine salinity tester is supplied complete with batteries and solutions allowing you to start measuring right away. Also displays temperature.
This pocket sized meter is waterproof and perfect for the measurement of salinity aquariums using conductivity to determine the salinity level of your water.
Salinity should be checked regularly in aquariums. As Oceans are very stable environments, where there is not a lot of day to day change in the water parameters, fish can respond negatively to even small changes in salinity.
Each meter is supplied with:
- CR2032 battery (installed)
- Storage/protection shield
- Instruction manual
- Quality certificate
- 35.00 ppt calibration standard sachet (x 4)
