HI83326 Multiparameter Photometer with Digital pH Electrode Input for Pool and Spa Applications The HI83326 benchtop photometer measures 12 dierent key water quality parameters using 14 dierent methods. This photometer features an innovative optical system that 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 pool and spa industry in mind, a basic necessity of pool water treatment is to maintain the water in a safe and pleasant condition for the swimmers. In pool and spa water treatment, disinfection is essential to rid the pool of bacteria and control nuisance organisms like algae which may occur in the pool, spa, ¡ltration equipment, or piping. There are a number of available disinfectant compounds including chlorine, bromine, and ozone. In order to achieve ideal water conditions, water requires testing on a daily and sometimes hourly basis to ensure there is enough residual disinfectant and to maintain pH levels. Equally important is calcium hardness and alkalinity; these levels should be monitored weekly to ensure the pool or spa water is well balanced to avoid corrosion and scale formation. • 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 • Data Logging · Up to 1000 photometric and pH readings can be stored by simply pressing the dedicated LOG button. Logged readings are just as easily recalled by pressing the RCL button · Sample ID and User ID information can be added to a logged reading using the alphanumeric keypad • Connectivity · Logged readings can be quickly and easily transferred to a flash drive using the USB-A host port or to a computer using the micro USB-B port · Data is exported as a .CSV file for use with common spreadsheet programs • Cuvette Cover · Aids in preventing stray light from affecting measurements • Rechargeable Battery · Li-polymer rechargeable battery lasts for 500 measurements or 50 hours of pH measurement • Battery Status Indicator · Indicates the amount of battery life left • Error Messages · Photometric error messages · pH calibration messages include clean electrode, check buffer and check probe HI83326-11 10 Photometers 10.58 | www.hannainst.com benchtop
