One meter can be used for both photometric and pH measurements. This meter has 23 different programmed methods measuring 15 key water quality parameters and also offers an absorbance measurement mode for performance verification and for users that would like to develop their own concentration versus absorbance curves. Water conditioning parameters include Fluoride, Chlorine, Ammonia, Manganese, Copper, Iron, Silver and Zinc.

The Hanna Instruments-83308 benchtop photometer measures 15 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. It ensures accurate and repeatable photometric readings every time.

The Hanna Instruments-83308 was developed to measure the most common parameters in water quality monitoring. One important parameter to test water quality is iron since it can affect colour, odour, and turbidity and can also be the most troublesome factor for appliances and surfaces in contact with water. High levels of iron in water can result in clogged water pipes or heat exchangers.

Additionally, Ammonia detection in water treatment systems is particularly important for aquarium owners and fish farm operators since ammonia is highly soluble in water and extremely toxic to fish. One other important parameter in water quality monitoring is Fluoride. Fluoride is best known for preventing tooth decay. While it does help prevent tooth decay, too little fluoride can be ineffective while too much can cause staining of teeth.

A digital pH electrode input allows the user to measure pH by a traditional glass electrode.

The Hanna Instruments-83308 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.

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 and 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 Hanna Instruments-83300 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 Hanna Instruments-83308 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.
