Hanna HI98319 Marine Salinity Tester - Waterproof ppt/PSU/S.G. for Aquariums & Seawater HI98319 and the light-blocking packaging ensures

and the light-blocking packaging ensures each sachet remains accurate until you're ready to use it

pre-measured reagents provide approximately 110 tests using the mercuric nitrate titration method for chloride determination in water samples ranging from 0 to 1000 mg/L (ppm)

The HI96822 contains a built-in temperature sensor and is programmed specialized algorithms then apply temperature compensation to the measurement and convert the refractive index to PSU (Practical Salinity Units)

simply soak the pH electrode in MA9016 cleaning solution

Hanna HI98319 Marine Salinity Tester - Waterproof ppt/PSU/S.G. for Aquariums & Seawater HI98319 and the light-blocking packaging ensuresDesigned to bring simplicity to salinity testing, the HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are digitally displayed on the LCD. Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S. G.). Comes with all the necessary solutions and batteries everything you need to get started
