KH Alkalinity - Carbonate Hardness Water Analysis
Alkalinity is essentially a means of quantifying the stability of pH in a solution, such as aquarium water. It is a measure of the concentration of various negatively charged ionic compounds (anions) such as carbonates, bicarbonates, borate and hydroxides in the aquarium water. If left unchecked, the alkalinity drops below a critical level and pH begins to fluctuate more wildly than is normally suggested (a daily pH shift of +/-0.2 is normal in marine aquaria), causing stress to livestock. In a marine aquarium, the alkalinity should be between 7° and 10° dKH (German carbonate hardness). In a fresh water aquarium it should never drop below 3° dKH.

Made In Italy
ELOS AquaTestKH makes it possible to quickly determine the buffering capacity of your aquarium water. It is an high quality product that offers high accuracy thanks to several procedures including: calibrated lab droppers with consistent and predefined drops size, NIST (National Institute of Standard and Technology) certified samples to validate reagents and strict stock management to supply to our customers ONLY the fresh test production batch available.
Calibrated Droppers - every drop administered is exactly the same size. You can do 1, 2, 3, 4x the test and the result will be always the same! Each predefined drop will produce 0.03 ml each of regent.
NIST (National Institute of Standard and Technology) certified batch Tested - Samples of each batch produced is sent out to NIST to validate the test reagents for accuracy and consistency.*
Expiration dates, batch and lot numbers in every kit and every reagent - Careful batch management and proper storage within a stable environment results in full life of the test kit
Packaging, instructions and reagents are clearly labelled - Written and illustrated instructions along with professionally calibrated color charts, makes every elos test kit easy to understand and use.
Grading: each drop equals 0.5 dKH°
* a sample of each batch of regents is sent to NIST (National Institute of Standard and Technology) a independent seawater lab for accuracy.
