Salifert KH/Alk Test Kit (Carbonate Hardness/Alkalinity)
The Salifert KH/Alk test is very straightforward.
It measures in sufficient small steps of 0.1 meq/L or 0.3 dKH with a sharp color change.
This makes detection of important yet small change possible.
The kit can perform approx. 100 – 200 measurements.
