The Hanna Instruments-83325 benchtop photometer measures 8 different plant nutrient water quality parameters using 9 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. Key parameters are: Ammonia, Calcium, Magnesium, Nitrate, Phosphorus, Potassium, Sulphate and pH.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eHanna Instruments-83325-02 Plant Nutrient Analysis Photometer with pH meter\u003c\/h3\u003e\n\u003cp\u003eAdvanced optical system - Unparalleled performance from a benchtop photometer.\u003c\/p\u003e\n\u003cp\u003eConsistent and thorough monitoring of plant nutrients is essential to maintaining healthy growth and reproduction. This is easy with the Hanna Instruments-83325, a comprehensive way to monitor vital plant nutrients such as potassium, calcium and magnesium. Required in large quantities, potassium plays a vital role in water uptake and enzyme regulation. Calcium helps to strengthen plant cell walls protecting against heat stress while magnesium helps build a strong immune system.\u003c\/p\u003e\n\u003cp\u003eA digital pH electrode input allows the user to measure pH by a traditional glass electrode.\u003c\/p\u003e\n\u003cp\u003eThe Hanna Instruments-83325 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 (420 nm, 466 nm, and 525 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.\u003c\/p\u003e\n\u003cp\u003eTwo USB ports are provided for transferring data to a flash drive or computer and to use as a power source for the meter.

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.\u003c\/p\u003e\n\u003ch3\u003eHigh Quality Narrow Band Interference Filters\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eReference Detector for a Stable Light Source\u003c\/h3\u003e\n\u003cp\u003eA 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.

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.\u003c\/p\u003e\n\u003ch3\u003eFocusing Lens for Greater Light Yield\u003c\/h3\u003e\n\u003cp\u003eAdding 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.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":40354376482967,"sku":"HI-83325-02","price":853.86,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/products\/heater_4_244ef4df-8e10-4227-a272-550e2bc9fb4e.jpg?v=1624278870"},{"product_id":"hanna-instruments-4111-iodine-combination-electrode","title":"Hanna Instruments-4111 Iodine Combination Electrode","description":"The Hanna Instruments-4111 is ideal for a variety of applications in food production and environmental monitoring.\u003cbr\u003e\u003cp\u003eThe Hanna Instruments-4111 iodide selective electrode is a complete potentiometric cell that contains a silver\/silver chloride (Ag\/AgCl) reference housed within a PEI plastic body with a potassium nitrate electrolyte.
