Description
The multiparameter photometer with COD measuring range and digital pH meter (230 V) is a compact benchtop instrument for essential water and wastewater quality analysis. An advanced optical system with reference detector and focusing lens reduces errors from light-source drift and cuvette imperfections, delivering accurate, reproducible photometric results. Forty key water and wastewater parameters are covered by 73 pre-programmed methods spanning multiple concentration ranges, including chemical oxygen demand (COD), total nitrogen and total phosphorus for municipal and industrial applications. An absorbance mode supports CAL Check verification and user-created concentration-versus-absorbance curves at five wavelengths (420 nm, 466 nm, 525 nm, 575 nm and 610 nm). From manufacturer Hanna Instruments, the unit also functions as a laboratory pH meter via a digital electrode input (electrode not supplied), accepting 3,5 mm jack digital electrodes that store calibration data on-board. Dual USB ports handle data transfer and 5 V power; an internal 3,7 V lithium-polymer battery permits up to 500 photometric measurements or 50 hours of pH operation. A backlit graphic LCD with virtual keys aids operation even in low light.

Questions about Multiparameter photometer, with COD and with digital pH (230V)
What is this article?
Multiparameter photometer, with COD and with digital pH (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.
