- The HI83326 benchtop photometer measures 11 different key water quality parameters using 12 different methods. This photometer features an innovative optical system that uses LEDs, 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.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, filtration 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.A digital pH electrode input allows 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.
The HI83326 offers an absorbance measuring mode that allows for CAL Check standards to be used to validate the performance of the system. The absorbance mode allows the user to select one of the three wavelengths of light (525 nm, 575 nm, and 610 nm) to measure and plot their own concentration versus absorbance mode. This is useful for users with their own chemical method and for educators to teach the concept of absorbance by using the Beer-Lambert Law.
Two USB ports are provided for transferring data to a flash drive or computer and to use as a power source for the meter. For added convenience and portability the meter can also operate on an internal 3.7 VDC Lithium-polymer rechargeable battery.
