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 Dissolved oxygen & multiparameter meters, inside pH & electrochemistry, in Lab instruments.
A dissolved-oxygen meter reads oxygen in a liquid, optically or with a Clark cell. A multiparameter meter adds pH, conductivity or both on one instrument. The sensor cap or the membrane is the consumable. A reading in air and a reading in water are different calibrations.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
