Description
The VISOCOLOR® alpha test kit for residual hardness (°d) is a dedicated visual test system for determining residual water hardness in degrees German hardness. Offered as a single complete unit, it supports laboratories, service technicians, and process teams that need a compact colour-based hardness check without heavy instrumentation. The kit sits within the VISOCOLOR® alpha line and addresses water hardness determination as well as broader visual parameter assessment. Density is approximately 1 g/cm³, and the unit weighs 0,051 kg, favouring easy handling and economical storage. Manufacturer data also list UN number 3316 for transport classification of the kit contents. Residual hardness screening is relevant in boiler feed, softener control, and general water-treatment workflows where °d values guide further action. This residual hardness °d kit from manufacturer MACHEREY-NAGEL is positioned for practical field and bench use within physical-property and hardness-testing applications. The one-piece pack simplifies inventory and ensures each station receives a full working set. Always consult the safety data sheet before use and follow site procedures for handling and disposal of test reagents.

Questions about VISOCOLOR® alpha test kit, rest hardness °d, 1 unit(s)
What is this article?
VISOCOLOR® alpha test kit, rest hardness °d, 1 unit(s) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Colorimetric test kits, inside Test kits & water analysis, in Lab chemicals.
A colorimetric kit develops a colour whose intensity tracks concentration. Comparing by eye against a chart and reading a photometer are different versions. The range, the sample volume and the interfering substances named in the leaflet are the specification.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
Which category should I open next?
The category is Test kits & water analysis. The sub-category is Colorimetric test kits. The catalogue is Lab chemicals.
