Description
The HI83306 benchtop photometer uses 23 different methods to measure 16 different key water quality parameters. This photometer has an innovative optical system that employs LEDs, narrow band interference filters, a focusing lens, and both a silicon photodetector for absorbance measurement and a reference detector to ensure accurate and repeatable photometric readings every time.
The HI83306 was designed to measure the most common environmental water quality parameters. Nitrates and phosphates, for example, are key indicators of nutrient pollution from agricultural sources and are considered hazardous to environmental waters. Too few nutrients and waters will be unable to sustain healthy ecosystems; too many nutrients and algal blooms will form, threatening water quality and aquatic health. Many forms of aquatic life, such as fish, plants, and microorganisms, rely on dissolved oxygen to perform biological processes.
A digital pH electrode input enables the user to measure pH using a standard glass electrode. The digital pH electrode incorporates a microchip within the probe that stores all calibration data. Because the calibration information is stored in the probe, it is possible to swap pH electrodes without having to recalibrate. With a built-in thermistor located in the tip of the sensing bulb for fast and accurate temperature measurement, all pH measurements are automatically compensated for temperature variations.
The HI83306 has an absorbance measuring mode that allows CAL Check standards to be used to validate the system’s performance. The absorbance mode allows the user to measure and plot their own concentration versus absorbance mode by selecting one of four light wavelengths (420 nm, 525 nm, 575 nm, and 610 nm). This is helpful for users who have their own chemical method as well as educators who want to teach the concept of absorbance using the Beer-Lambert Law.
There are two USB ports for transferring data to a flash drive or computer and powering the meter. The meter can also run on an internal 3.7 VDC Lithium-polymer rechargeable battery for added convenience and portability.

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 ensures 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 focuses the light on the silicon photodetector. 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.
