Description
Test strips with four indicators for pH 7,0 to pH 14,0 enable fast visual determination of neutral to strongly alkaline samples in laboratory settings. The vinyl strips neither decolourise nor colour the solution under test, even when the medium is strongly alkaline, helping preserve the appearance and integrity of the measured liquid. The measurement is more precise than with conventional pH test paper, and the colour change remains visible for longer, which aids reliable comparison with the colour chart. Supplied in boxes of 100 strips, the pack format suits frequent spot checks, educational laboratories and quality-control screening. These METRIA products from manufacturer Labbox are intended for straightforward dip-and-read use on aqueous systems when instrumental pH measurement is unnecessary or unavailable. The multi-indicator design on each strip supports a clear response across the full 7,0–14,0 alkaline-side interval. With a net weight of 0,060 kg per pack, the unit is compact for storage and bench distribution. Suitable for general laboratory orientation of alkaline pH within the stated range.
