The Kusuri line of visual test kits, which are the best available, all use Palintest technology components.
All kits come with non-biodegradable foil-sealed tablets and a plastic acetate card that is simple to match colours.
The following water parameters will be tested ten times each: ammonia, nitrite, nitrate, ph, and k.



This is what the "one off" range principle means.
We include plenty of information on water quality in our kits, so the proper action can be taken if results are not as expected. Buy it once, and you can reload your kit with refill tablets (for 50 tests) or any other components needed.
