Wastewater Multiparameter (with COD) Benchtop Photometer and pH meter
HI83314 benchtop photometer measures 10 different key wastewater quality parameters using 20 different methods that allow for multiple ranges and variations in chemistry for specific applications. The Chemical Oxygen Demand (COD) parameter is included for industrial and municipal wastewater treatment. The Phosphorous and Nitrogen parameters included are beneficial to municipal wastewater treatment customers that need to monitor their biological and chemical nutrient removal process. This photometer features an innovative optical system that uses LED’s, narrow band interference filters, focusing lens and both a silicon photodetector for absorbance measurement and a reference detector to maintain a consistent light source ensures accurate and repeatable photometric readings every time.
A digital pH electrode input is provided allowing the user to measure pH by a traditional glass electrode. The digital pH electrode has a built in microchip within the probe that stores all of the calibration information. Having the calibration information stored in the probe allows for hot swapping of pH electrodes without having to recalibrate. All pH measurements are automatically compensated for temperature variations with a built in thermistor located in the tip of the sensing bulb for fast and accurate temperature measurement.
