Description
Photometer PF-3 Soil is a compact photometer supplied in a sturdy case together with VISOCOLOR ECO test kits for ammonium 3, potassium, nitrate and phosphate. The set further includes a calibration cuvette, four empty cuvettes, a sample cup, a 5 ml syringe, three batteries, a handbook, the VISOCOLOR ECO test instructions booklet for the compact photometer PF-3 and a certificate. Configured for soil and water analysis, the instrument serves as the optical evaluation unit for the included VISOCOLOR ECO chemistry and remains suitable for additional compatible test formats used in routine photometric work. This compact photometer from manufacturer Macherey-Nagel arrives as a ready-to-use field and laboratory package for key nutrient and soil parameters. Net weight is 2,25 kg. The robust case organises optics, accessories and test kits for transport between sampling sites and the bench, supporting environmental monitoring, agricultural testing and quality-control workflows that rely on clear photometric results.

Questions about Photom. PF-3 Soil, reagent case
What is this article?
Photom. PF-3 Soil, reagent case is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Instruments de précision.
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.
Which category should I open next?
The category is Spectroscopy & photometry. The sub-category is Photometers & spectrophotometers. The catalogue is Instruments de précision.
Shelves beside this one are Refractometers & polarimeters and Lamps, cuvette holders & accessories.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
