The Palintest® technology components found in the Salinity Test Kit make it one of the best visual test kits available.
Approximately 30 tests can be performed with the salinity test kit.
This is what the "one off" range principle means.
We include plenty of information on the quality of the water in our kits, so the proper action may be taken if results are not what was expected. Buy it once and you can renew your kit with refill tablets or any other components needed.
