Its optical design pairs a reference detector with a focusing lens, which removes errors caused by drift in the light source and by imperfections in the glass cuvette. Forty water and wastewater parameters are programmed in, covered by 73 methods spanning multiple ranges. The digestion parameters include COD, Total Nitrogen and Total Phosphorus, the measurements that matter most when nutrient removal is being monitored. An absorbance mode is available for performance verification and for anyone developing their own concentration versus absorbance curves, and the digital pH and temperature electrode input lets the same instrument serve as a professional pH meter, saving a second footprint on the bench.\u003c\/p\u003e\n\u003cul style=\"margin: 0 0 16px; padding-left: 22px;\"\u003e\n\u003cli style=\"margin-bottom: 8px;\"\u003eAdvanced optical system\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px;\"\u003eUnparalleled performance from a benchtop photometer\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px;\"\u003eDigital pH electrode input\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px;\"\u003eOne instrument that works as both photometer and laboratory pH meter\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px;\"\u003eWater and wastewater treatment digestion parameters\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px;\"\u003eMeasures COD, Total Nitrogen and Total Phosphorus\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/section\u003e\u003csection class=\"btsx-hanna-sec\" style=\"border-bottom: 1px solid #e0e0e0; margin: 0 0 clamp(24px, 4vw, 40px); padding-bottom: clamp(24px, 4vw, 40px); min-width: 0; box-sizing: border-box;\"\u003e\u003cp style=\"margin: 0 0 16px;\"\u003eThe benchtop photometer measures 40 different key water and wastewater quality parameters using 73 methods, which allow for multiple ranges and for variations in chemistry that suit specific applications. Chemical Oxygen Demand is included for industrial and municipal wastewater treatment, and the phosphorus and nitrogen parameters serve municipal plants monitoring biological and chemical nutrient removal. The optical system behind those readings combines LEDs, narrow band interference filters and a focusing lens with both a silicon photodetector for absorbance and a reference detector that holds the light source consistent.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 16px;\"\u003eA digital pH electrode input allows pH to be measured with a traditional glass electrode. The digital electrode carries a microchip inside the probe that stores its own calibration information, so electrodes can be hot swapped without recalibrating. Every pH measurement is compensated for temperature automatically by a thermistor in the tip of the sensing bulb.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 16px;\"\u003eTwo USB ports handle data transfer to a flash drive or a computer and can also power the meter.

In that mode one of five wavelengths — 420 nm, 466 nm, 525 nm, 575 nm or 610 nm — can be selected and plotted as concentration against absorbance, which suits laboratories running their own chemistry and teaching work built on the Beer-Lambert Law.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 16px;\"\u003eReagents are not included with the meter.\u003c\/p\u003e\u003c\/section\u003e\u003csection class=\"btsx-hanna-sec\" style=\"border-bottom: 1px solid #e0e0e0; margin: 0 0 clamp(24px, 4vw, 40px); padding-bottom: clamp(24px, 4vw, 40px); min-width: 0; box-sizing: border-box;\"\u003e\u003ch2 class=\"btsx-hanna-h\" style=\"font-family: 'Open Sans', Arial, Helvetica, sans-serif; font-weight: 400; font-size: 1rem; margin: 0 0 20px; min-width: 0;\"\u003eFeatures and Benefits\u003c\/h2\u003e\n\u003cdiv class=\"btsx-hanna-row\" style=\"display: flex; flex-wrap: wrap; gap: clamp(20px, 4vw, 40px); min-width: 0; box-sizing: border-box;\"\u003e\n\u003cdiv class=\"btsx-hanna-col\" style=\"flex: 1 1 500px; min-width: 0; max-width: 100%; box-sizing: border-box;\"\u003e\u003cp style=\"margin: 0 0 16px;\"\u003e\u003cstrong style=\"font-weight: 700;\"\u003eDigital pH Electrode Input\u003c\/strong\u003e\u003cbr\u003eMeasure pH and temperature with one probe.
