Kusuri Ph Test Kit

A plastic acetate colour match chart with breaks at 6.8/7.0/7.2/7.5/7.8/8.0/8.4 and three 10-tablet foil-sealed tablets make up the Kusuri pH Test Kit.


Guidelines for water quality are also provided, along with complete instructions.


The Kusuri line of visual test kits, which are the best available, all use Palintest technology components.


The Kusuri pH Test Kit comes with non-biodegradable foil-sealed tablets and a plastic acetate card that is simple to match in colour.
There are 30 tests in each kit.
The "one off" range principle really means just that!
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.


An accurate plastic acetate colour strip is a feature of Kusuri Test Kits.
It is much simpler to compare when held up to a light source than a paper printed chart.
