HI83303 Multiparameter Photometer with Digital pH Electrode Input for Aquaculture The HI83303 benchtop photometer measures 12 dierent key water quality parameters using 20 dierent methods. This photometer uses an LED, a narrow band interference ¡lter, a focusing lens, and both a silicon photodetector for absorbance measurement and a reference detector to maintain a consistent light source to ensure accurate and repeatable photometric readings every time. Made with the aquaculture industry in mind, the HI83303 is a comprehensive solution to maintaining optimal chemical and environmental conditions, preventing disease, and increasing production. The HI83303 measures vital parameters such as alkalinity, calcium, nitrite, and phosphate. Alkalinity plays a part in a dynamic relationship with pH and COº concentrations, high alkalinity water lowers uctuations in pH. The buering capacity acts to store extra COº essential for photosynthesis in ponds to produce oxygen. Maintaining calcium at certain levels is vital to proper ¡sh growth and development. Excessive nitrite can be toxic to ¡sh. When nitrite interacts with hemoglobin the iron becomes oxidized and blood cells can no longer carry oxygen. Phosphate is essential to plant growth; too much phosphate in an aquaculture system can contribute to algal blooms decreasing dissolved oxygen vital for a successful ecosystem. • Advanced optical system · Innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette • Backlit 128 x 64 Pixel Graphic LCD Display · Backlit graphic display allows for easy viewing in low light conditions · The 128 x 64 Pixel LCD allows for a simplified user interface with virtual keys and on-screen help to guide the user through use of the meter • Built-in Reaction Timer for Photometric Measurements · The measurement is taken after the countdown timer expires. · Countdown timer ensures that all readings are taken at the appropriate reaction intervals regardless of user for better consistency in measurements • Absorbance mode · Hanna's exclusive CAL Check™ cuvettes for validation of light source and detector · Allows for the user to plot concentration versus absorbance for a specific wavelength for use with user supplied chemistry or for teaching principles of photometry • Units of Measure · Appropriate unit of measure along with chemical form is displayed along with reading • Result Conversion · Automatically convert readings to other chemical forms with the touch of a button • Cuvette Cover · Aids in preventing stray light from affecting measurements • Digital pH Electrode Input · Measure pH and temperature with a single probe · Good Laboratory Practice (GLP) to track calibration information including date, time, buffers used, offset and slope for traceability · pH CAL Check™ alerts user to potential problems during the calibration process · Space saving having a pH meter and photometer built into one meter • Battery Status Indicator · Indicates the amount of battery life left • Data Logging · Up to 1000 photometric and pH readings can be stored by simply pressing the dedicated LOG button.
