The HI83306 benchtop photometer measures 16 different key water quality parameters using 23 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.
The HI83306 was developed to measure the most common parameters in environmental water quality monitoring. Nutrients such as nitrates and phosphates are key indicators of nutrient pollution from agricultural sources and are considered dangerous to environmental waters.Too few nutrients and waters will be unable to sustain healthy ecosystems; too many nutrients and algal blooms can form, which can be detrimental to water quality and aquatic health. Dissolved oxygen is an essential to performing biological processes for many forms of aquatic life, such as fish, plants and microorganisms.
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 HI83306 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 four wavelengths of light (420 nm, 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.

pH Measurement Mode
Selecting the pH measurement mode allows for the photometer to be used as a professional pH meter with many features including temperature compensated measurements, automatic two point calibration, and GLP.
Advanced Optical System
HI83306 is designed with an innovative optical system that incorporates a beam splitter so that light can be used for absorbance readings and for a reference detector. The reference detector monitors the intensity of light and modulates when there is drift due to power fluctuation or the heating of the optical components. Each part has an important role in providing unparalleled performance from a photometer.
High Efficiency LED Light Source
An LED light source offers superior performance as compared to a tungsten lamp. LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce very little heat, which could otherwise affect the optical components an electronic stability. LEDs are available in a wide array of wavelengths, whereas tungsten lamps are supposed to be white light (all wavelengths of visible light) but actually have a poor blue/violet light output.
High Quality Narrow Band Interference Filters
The narrow band interference filter not only ensure greater wavelength accuracy (+/- 1 nm) but are extremely efficient. The filters used allow up to 95% of the light from the LED to be transmitted as compared to other filters that are only 75% efficient. The higher efficiency allows for a brighter, stronger light source. The end result is higher measurement stability and less wavelength error.
Reference Detector for a Stable Light Source
A beam splitter is used as part of the internal reference system of the HI83306 photometer. The reference detector compensates for any drift due to power fluctuations or ambient temperature changes. Now you can rely on a stable source of light between your blank (zero) measurement and sample measurement.
Large Cuvette Size
The sample cell of the HI83306 fits a round, glass cuvette with a 25 mm path length. Along with the advanced optical components, the larger size of the cuvette greatly reduces errors in rotation from the indexing mark of the cuvettes. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples.
Focusing Lens for Greater Light Yield
Adding a focusing lens to the optical path allows for the collection of all of the light that exits the cuvette and focusing the light on the silicon photo detector. This novel approach to photometric measurements cancels the errors from imperfections and scratches present in the glass cuvette eliminating the need to index the cuvette.
