Description
pH reagents for photometer (100 tests) are formulated for the photometric determination of pH in the working range from 5,9 to 8,5 by the phenol red method. This colorimetric approach supports laboratories that measure near-neutral pH on compatible photometers when electrode systems are not preferred or when optical pH checks form part of a defined analytical workflow. Each pack covers one hundred tests, providing a convenient quantity for routine batches, teaching practicals, or ongoing quality-control sequences. Net weight is 0,055 kg and gross weight is 1,055 kg, corresponding to a compact reagent kit that is easy to store beside the instrument. These reagents from manufacturer Hanna Instruments address photometric pH determination strictly within the stated 5,9–8,5 interval using phenol red chemistry, matching common needs in water testing and general laboratory spectroscopy accessories. Country of origin is Romania. The product is supplied as a single pack unit, simplifying stock management and reorder cycles for facilities that rely on photometric pH reagents alongside other colorimetric test sets.

What is this article?
pH, phenol red method, Reagent kit for 100 tests (pH) is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Lab instruments.
A photometer reads absorbance at one or a few wavelengths. A spectrophotometer scans or selects many. Both send light through a cuvette or a well. The wavelength range, UV or visible, and the bandwidth decide what can be measured. A visible-only instrument cannot read a nucleic acid at 260 nm.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
