Description
Multiparameter benchtop photometer with digital pH meter for NPK analyses (230 V) is a compact instrument for nutrient-related water quality work in the laboratory or in the field. An advanced optical layout with reference detector and collecting lens helps limit errors from light-source drift and cuvette imperfections, supporting accurate, reproducible photometric results. The unit covers eight key plant-nutrient water quality parameters via nine pre-programmed methods and also offers an absorbance mode for system checks and user-built concentration-versus-absorbance curves at selectable wavelengths of 420 nm, 466 nm and 525 nm. A digital pH electrode input lets the same bench footprint serve as a laboratory pH meter when a compatible 3,5 mm jack digital electrode is connected (electrode not included); onboard microchip calibration data and tip thermistor support automatic temperature compensation. Dual USB ports handle data transfer and 5 V power, while an internal 3,7 V lithium-polymer battery enables roughly 500 photometric readings or 50 hours of pH measurement away from mains. A backlit graphic LCD with virtual keys and multilingual help, including German menus, simplifies operation. This multiparameter photometer from manufacturer Hanna Instruments is supplied as 1 pc for NPK-focused analytical workflows.

Questions about Multiparameter photometer and pH meter for Plants Nutrient analysis (230V)
What is this article?
Multiparameter photometer and pH meter for Plants Nutrient analysis (230V) 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.
