Description
Reagents for photometer, total hardness (100 tests, all measuring ranges) provide a complete set for photometric determination of total hardness across low, medium and high ranges. The pack comprises 100 tests for the low range (0–250 mg/L), 100 tests for the medium range (200–450 mg/L; 12–30 °dH) and 100 tests for the high range (400–750 mg/L; 24–42 °dH), giving full coverage of common hardness levels in water analysis. This configuration supports laboratories that need flexible hardness testing without stocking separate kits for each interval. The reagents are from manufacturer Hanna Instruments and are intended for use with compatible photometers in routine water quality control, process monitoring and environmental assessment. Net weight is 4,09 kg and gross weight is 5,09 kg, reflecting the multi-range content of the unit. Hazard information includes the signal word Danger and corresponding GHS classifications, so standard laboratory protective measures apply during use. These reagents belong to other spectroscopy articles and deliver a practical consumable solution for total hardness photometry over all stated measuring ranges.
This article is part of Photometers & spectrophotometers, in Spectroscopy & photometry.

What is this article?
Reagent kit for photometer, Hardness, total, (100 tests, all ranges) 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.
